Dear all, We are pleased to let you know that we have just published a JGR paper: Construction of Temperature Climate Data Records in the Upper Troposphere and Lower Stratosphere Using Multiple RO Missions From September 2006 to July 2023 at NESDIS/STAR Jun Zhou <https://agupubs.onlinelibrary.wiley.com/authored-by/Zhou/Jun>, Shu-Peng Ho <https://agupubs.onlinelibrary.wiley.com/authored-by/Ho/Shu%E2%80%90Peng> , Xinjia Zhou <https://agupubs.onlinelibrary.wiley.com/authored-by/Zhou/Xinjia>, Xi Shao <https://agupubs.onlinelibrary.wiley.com/authored-by/Shao/Xi>, Guojun Gu <https://agupubs.onlinelibrary.wiley.com/authored-by/Gu/Guojun>, Yong Chen <https://agupubs.onlinelibrary.wiley.com/authored-by/Chen/Yong>, Tung-Chang Liu <https://agupubs.onlinelibrary.wiley.com/authored-by/Liu/Tung%E2%80%90Chang> , Xin Jing <https://agupubs.onlinelibrary.wiley.com/authored-by/Jing/Xin> First published: 09 June 2025 https://doi.org/10.1029/2024JD041295 https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2024JD041295 One of the key findings is summarized in Figure 7, which demonstrates the RO-RO biases for COSMIC-1 - Metop GRAS, Spire - Metop GRAS, and COSMIC2 - Metop GRAS. The temperature MMC CDR in the UT/LS is constructed using COSMIC-1, Metop-A, -B, -C GRAS, and Spire.
