Amplitude scintillation index derived from C/N0 measurements released by common geodetic GNSS receivers operating at 1 Hz
Abstract Two widely used scintillation indexes %$ S_{4} %$ and %$ \sigma_{\varphi } %$ are generated by dedicated ionospheric scintillation monitoring receivers (ISMRs), which typically have 50-Hz temporal resolution and thus require substantial memory capabilities. Taking into consideration the hug...

| 520 | |a Abstract Two widely used scintillation indexes %$ S_{4} %$ and %$ \sigma_{\varphi } %$ are generated by dedicated ionospheric scintillation monitoring receivers (ISMRs), which typically have 50-Hz temporal resolution and thus require substantial memory capabilities. Taking into consideration the huge number of common Global Navigation Satellite System (GNSS) receivers, the derivation of a GNSS receiver-based scintillation index as a supplement to the ISMR indexes is expected to improve the study of ionospheric scintillation. We developed an amplitude scintillation index, %$ S_{{4{\text{c}}}} %$, which is derived from the carrier-to-noise density ratio (%$ C/N_{0} %$) data released by common geodetic GNSS receivers operating at 1-Hz. The reliability of the %$ S_{{4{\text{c}}}} %$ index is compared with the typical scintillation index %$ S_{4} %$ of three ISMRs located in Hong Kong and Brazil. The statistics indicate that during scintillation activity, the correlation coefficient between %$ S_{{4{\text{c}}}} %$ (derived from common receivers) and %$ S_{4} %$ (generated by ISMRs) is generally higher than 0.9. The reliability of %$ S_{{4{\text{c}}}} %$ was also verified based on 1-year observations from two adjacent stations in Hong Kong, which are equipped with Leica GR50 and Septentrio PolaRxS Pro receivers, respectively. Long-term scintillation occurrence (%$ S_{{4{\text{c}}}} %$ > 0.2 vs. %$ S_{4} %$ > 0.2) rates show good agreement between %$ S_{{4{\text{c}}}} %$ and %$ S_{4} %$. In addition, two-dimensional %$ S_{{4{\text{c}}}} %$ maps (1° × 1°) generated by GPS L1 and BDS B1 signals data collected at 117 continuous operation tracking stations in China clearly show post-sunset super plasma bubbles as the source of ionospheric scintillation during the main phase of the intense storm that occurred on September 8, 2017. These results demonstrate the feasibility of using the %$ S_{{4{\text{c}}}} %$ index derived from the large volume of GNSS observations recorded by non-scintillation GNSS receivers for the study and monitoring of ionospheric scintillation. | ||

Taking into consideration the huge number of common Global Navigation Satellite System (GNSS) receivers, the derivation of a GNSS receiver-based scintillation index as a supplement to the ISMR indexes is expected to improve the study of ionospheric scintillation. We developed an amplitude scintillation index, %$ S_{{4{\text{c}}}} %$, which is derived from the carrier-to-noise density ratio (%$ C/N_{0} %$) data released by common geodetic GNSS receivers operating at 1-Hz. The reliability of the %$ S_{{4{\text{c}}}} %$ index is compared with the typical scintillation index %$ S_{4} %$ of three ISMRs located in Hong Kong and Brazil. The statistics indicate that during scintillation activity, the correlation coefficient between %$ S_{{4{\text{c}}}} %$ (derived from common receivers) and %$ S_{4} %$ (generated by ISMRs) is generally higher than 0.9. The reliability of %$ S_{{4{\text{c}}}} %$ was also verified based on 1-year observations from two adjacent stations in Hong Kong, which are equipped with Leica GR50 and Septentrio PolaRxS Pro receivers, respectively. Long-term scintillation occurrence (%$ S_{{4{\text{c}}}} %$ > 0.2 vs. %$ S_{4} %$ > 0.2) rates show good agreement between %$ S_{{4{\text{c}}}} %$ and %$ S_{4} %$.

Taking into consideration the huge number of common Global Navigation Satellite System (GNSS) receivers, the derivation of a GNSS receiver-based scintillation index as a supplement to the ISMR indexes is expected to improve the study of ionospheric scintillation. We developed an amplitude scintillation index, %$ S_{{4{\text{c}}}} %$, which is derived from the carrier-to-noise density ratio (%$ C/N_{0} %$) data released by common geodetic GNSS receivers operating at 1-Hz. The reliability of the %$ S_{{4{\text{c}}}} %$ index is compared with the typical scintillation index %$ S_{4} %$ of three ISMRs located in Hong Kong and Brazil. The statistics indicate that during scintillation activity, the correlation coefficient between %$ S_{{4{\text{c}}}} %$ (derived from common receivers) and %$ S_{4} %$ (generated by ISMRs) is generally higher than 0.9. The reliability of %$ S_{{4{\text{c}}}} %$ was also verified based on 1-year observations from two adjacent stations in Hong Kong, which are equipped with Leica GR50 and Septentrio PolaRxS Pro receivers, respectively. Long-term scintillation occurrence (%$ S_{{4{\text{c}}}} %$ > 0.2 vs. %$ S_{4} %$ > 0.2) rates show good agreement between %$ S_{{4{\text{c}}}} %$ and %$ S_{4} %$. In addition, two-dimensional %$ S_{{4{\text{c}}}} %$ maps (1° × 1°) generated by GPS L1 and BDS B1 signals data collected at 117 continuous operation tracking stations in China clearly show post-sunset super plasma bubbles as the source of ionospheric scintillation during the main phase of the intense storm that occurred on September 8, 2017. These results demonstrate the feasibility of using the %$ S_{{4{\text{c}}}} %$ index derived from the large volume of GNSS observations recorded by non-scintillation GNSS receivers for the study and monitoring of ionospheric scintillation.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Scintillation indexes</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Carrier-to-noise density ratio (</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">)</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Ionospheric scintillation monitoring receivers (ISMRs)</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Common geodetic GNSS receivers</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Ionospheric irregularities and scintillations</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Gu, Shengfeng</subfield><subfield code="0">(orcid)0000-0001-6004-5938</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lou, Yidong</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Cai, Lei</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liu, Zhizhao</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of geodesy</subfield><subfield code="d">Berlin : Springer, 1995</subfield><subfield code="g">94(2020), 2 vom: 13.

Amplitude scintillation index derived from C/N0 measurements released by common geodetic GNSS receivers operating at 1 Hz |

Abstract Two widely used scintillation indexes %$ S_{4} %$ and %$ \sigma_{\varphi } %$ are generated by dedicated ionospheric scintillation monitoring receivers (ISMRs), which typically have 50-Hz temporal resolution and thus require substantial memory capabilities. Taking into consideration the huge number of common Global Navigation Satellite System (GNSS) receivers, the derivation of a GNSS receiver-based scintillation index as a supplement to the ISMR indexes is expected to improve the study of ionospheric scintillation. We developed an amplitude scintillation index, %$ S_{{4{\text{c}}}} %$, which is derived from the carrier-to-noise density ratio (%$ C/N_{0} %$) data released by common geodetic GNSS receivers operating at 1-Hz. The reliability of the %$ S_{{4{\text{c}}}} %$ index is compared with the typical scintillation index %$ S_{4} %$ of three ISMRs located in Hong Kong and Brazil. The statistics indicate that during scintillation activity, the correlation coefficient between %$ S_{{4{\text{c}}}} %$ (derived from common receivers) and %$ S_{4} %$ (generated by ISMRs) is generally higher than 0.9. The reliability of %$ S_{{4{\text{c}}}} %$ was also verified based on 1-year observations from two adjacent stations in Hong Kong, which are equipped with Leica GR50 and Septentrio PolaRxS Pro receivers, respectively. Long-term scintillation occurrence (%$ S_{{4{\text{c}}}} %$ > 0.2 vs. %$ S_{4} %$ > 0.2) rates show good agreement between %$ S_{{4{\text{c}}}} %$ and %$ S_{4} %$. In addition, two-dimensional %$ S_{{4{\text{c}}}} %$ maps (1° × 1°) generated by GPS L1 and BDS B1 signals data collected at 117 continuous operation tracking stations in China clearly show post-sunset super plasma bubbles as the source of ionospheric scintillation during the main phase of the intense storm that occurred on September 8, 2017. These results demonstrate the feasibility of using the %$ S_{{4{\text{c}}}} %$ index derived from the large volume of GNSS observations recorded by non-scintillation GNSS receivers for the study and monitoring of ionospheric scintillation. © Springer-Verlag GmbH Germany, part of Springer Nature 2020 |

These results demonstrate the feasibility of using the %$ S_{{4{\text{c}}}} %$ index derived from the large volume of GNSS observations recorded by non-scintillation GNSS receivers for the study and monitoring of ionospheric scintillation.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Scintillation indexes</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Carrier-to-noise density ratio (</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">)</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Ionospheric scintillation monitoring receivers (ISMRs)</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Common geodetic GNSS receivers</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Ionospheric irregularities and scintillations</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Gu, Shengfeng</subfield><subfield code="0">(orcid)0000-0001-6004-5938</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lou, Yidong</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Cai, Lei</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liu, Zhizhao</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of geodesy</subfield><subfield code="d">Berlin : Springer, 1995</subfield><subfield code="g">94(2020), 2 vom: 13.
