TL;DR: By approximating a line-by-line calculation of atmospheric transmittance with simplified analytical expressions for effective opacity, upwelling brightness temperatures for five passbands in the 183-GHz water-vapor line are obtained with the fidelity of 0.04 K or better in the mean and 0.06 K in the standard deviation as mentioned in this paper .
Abstract: By approximating a line-by-line calculation of atmospheric transmittance with simplified analytical expressions for effective opacity, upwelling brightness temperatures for five passbands in the 183-GHz water-vapor line are obtained with the fidelity of 0.04 K or better in the mean and 0.06 K or better standard deviation. The effect of weak ozone lines in or near the passbands is included by calculating their passband-average opacity. The passband-average opacity due to the water line is corrected to passband-average transmittance by a linear adjustment.

TL;DR: The SI-Traceable Space-based Climate Observing System Workshop (hereafter denoted SITSCOS) was hosted by the National Physical Laboratory in London, UK, 9-11 September 2019 and sponsored by the UK Space Agency as discussed by the authors .
Abstract: The SI-Traceable Space-based Climate Observing System Workshop (hereafter denoted SITSCOS) was hosted by the National Physical Laboratory in London, UK, 9-11 September 2019 and sponsored by the UK Space Agency. The workshop was organized under the auspices of the Global Space-based Inter-Calibration System (GSICS) and the Committee on Earth Observation Satellites - Working Group on Calibration and Validation (CEOS-WGCV). The goal of the workshop was to quantify the benefits and resulting requirements of a space-based climate observing system and produce this Workshop Report summarizing current measurement capabilities, climate-based needs, and future plans for implementation. The international workshop included about 100 attendees and spanned users, satellite instrument designer/builders, metrologists, and space agencies with expertise across a wide range of applications and technologies. This is the report of that workshop
