Gasso Participates in Remote Sensing International Workshop

December 7, 2021

On December 1 -3, two members of code 613 participated in an international workshop hosted by the European agency Eumesat and the SOLAS project: “Remote Sensing for Ocean-Atmosphere Interactions Studies and Applications Workshop”. The meeting had an assortment of presentations and discussion panels as well as demonstration of the web and cloud interfaces available for data discovery. Santiago Gassó (ESSIC) participated as one the science organizing committee members, as a panelist and convener.

Advanced Technology Microwave Sounder Radiance Data Products Calibration and Evaluation

November 22, 2021

ESSIC/CISESS Scientist Hu “Tiger” Yang has a new article on the Advanced Technology Microwave Sounder (ATMS) in press at IEEE Transactions on Geoscience and Remote Sensing. The Advanced Technology Microwave Sounder (ATMS) is a passive microwave radiometer for the current generation of polar-orbiting meteorological satellites operated by NOAA. The first two ATMS instruments are onboard the Suomi National Polar-orbiting Partnership (S-NPP) and NOAA-20 satellites. The article explains several critical changes in the ATMS operational calibration algorithm since March 2017. Details of the radiance-based ATMS on-orbit calibration are documented and results of pre-launch calibration error budget analysis and post-launch calibration accuracy evaluation are also presented.

Moradi is Co-I of NASA Proposal Developing A New Satellite Instrument

November 11, 2021

Traditional earth-observing microwave instruments utilize heterodyne receivers for measuring the radiance emitted by the earth and its atmosphere. These instruments which indirectly measure atmospheric temperature, water vapor, clouds, as well as surface information, have played an important role in improving the NWP weather forecasts and reanalyses, such as MERRA generated by GMAO. However, because of limitations in current microwave technologies in simultaneously processing an ultra-wide band (20-200 GHz) at high spectral resolutions, the number of channels for the current microwave instruments is very limited (e.g., 22 channels for ATMS and less for most other MW instruments).
