Experimental DORIS-Derived dSTEC Information The experimental dSTEC data derived from Jason-3 NRT DORIS observations can be accessed here: https://data.bdsmart.cn/pub/product/iono/nrtdoris/dstec/ Currently, only ionospheric dSTEC data from Jason-3 NRT DORIS observations are provided for the period DOY 019 �C 298, 2023. If you are interested in a longer time span of Jason-3 DORIS dSTEC data, please let me know. I can upload the full dataset if the currently provided products meet your requirements. Your feedback is highly appreciated! For further details on the generation of Jason-3 DORIS-dSTEC data and its use in validating GNSS-derived global TEC maps, please refer to the following publication: Ang Liu, Ningbo Wang, Denise Dettmering, Zishen Li, Michael Schmidt, Liang Wang, Hong Yuan (2023).* Using DORIS Data for Validating Real-Time GNSS Ionosphere Maps.
