The greenhouse gas observation mission with Global Observing SATellite for Greenhouse gases and Water cycle (GOSAT-GW): objectives, conceptual framework and scientific contribution... by Hiroshi Tanimoto, Tsuneo Matsunaga, Yu Someya, Tamaki Fujinawa, Hirofumi Ohyama, Isamu Morino, Hisashi Yashiro, Takafumi Sugita, Satoshi Inomata, Astrid Müller, Tazu Saeki, Yukio Yoshida, Yosuke Niwa, Makoto Saito, Hibiki Noda, Yousuke Yamashita, Kohei Ikeda, Nobuko Saigusa, Toshinobu Machida, Matthias Max Frey, Hyunkwang Lim, Priyanka Srivastava, Yoshitaka Jin, Atsushi Shimizu, Tomoaki Nishizawa, Yugo Kanaya, Takashi Sekiya, Prabir Patra, Masayuki Takigawa, Jagat Bisht, Yasko Kasai, Tomohiro O. Sato

“…It aims to retrieve the column-averaged dry-air mole fractions of CO2 and CH4 (denoted as XCO2 and XCH4, respectively), as well as the vertical column density of tropospheric NO2. The TANSO-3 sensor onboard GOSAT-GW will utilize the wavelength bands of 0.45, 0.76, and 1.61 µm for NO2, O2, and CO2 and CH4 retrievals, respectively. …”

Analysis of the long-range transport of the volcanic plume from the 2021 Tajogaite/Cumbre Vieja eruption to Europe using TROPOMI and ground-based measurements by P. Hedelt, J. Reichardt, F. Lauermann, B. Weiß, N. Theys, A. Redondas, A. Barreto, O. Garcia, D. Loyola

“…This study provides an analysis of <span class="inline-formula">SO₂</span> vertical column density (VCD) and layer height (LH) measurements of the volcanic plume obtained with Sentinel-5 Precursor/TROPOspheric Monitoring Instrument (TROPOMI), which are compared to the observations at several stations across the Canary Islands. …”

Aerosol layer height (ALH) retrievals from oxygen absorption bands: intercomparison and validation among different satellite platforms, GEMS, EPIC, and TROPOMI by H. Kim, H. Kim, X. Chen, X. Chen, J. Wang, J. Wang, J. Wang, J. Wang, Z. Lu, Z. Lu, Z. Lu, M. Zhou, G. R. Carmichael, G. R. Carmichael, S. S. Park, J. Kim

“…In this study, we evaluate ALH products retrieved using oxygen absorption measurements from multiple satellite platforms: the Geostationary Environment Monitoring Spectrometer (GEMS) focusing on Asia, the Earth Polychromatic Imaging Camera (EPIC) in deep space, and the polar-orbiting TROPOspheric Monitoring Instrument (TROPOMI). We use the extinction-weighted aerosol optical centroid height (AOCH) derived from aerosol extinction profiles of Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) as the ground truth. …”
