Earth


One of our goals is to analyze data from instruments onboard satellites and space platforms, and to develop concepts for future space missions to study the atmosphere of the Earth and surface-atmosphere interactions.
We are currently involved as co-Is in the development of the following space missions:

Ultraviolet Atmospheric Sensor (UVAS)/SeoSAT 

The Ultraviolet and Visible atmospheric Sounder (UVAS), currently in phase C of evaluation for the Spanish Earth Observation SATellite SEOSAT-INGENIO, which is to be launched in 2018, is a new generation instrument for Remote Sensing of Atmospheric Trace Gases. Its primary objective will be to provide global column density maps of trace gases and aerosols related to air quality, atmospheric pollution, anthropogenic greenhouse effect and halogen chemistry.

Microwave sounding instruments.

Many operational weather satellites and scientific satrellites on polar and tropical orbits have instruments using the microwave (MW) range for sounding of the atmosphere. Among those are MHS (AMSU, MetOp), SSMI/S (DMSP) and SAPHIR (MeghaTropiques). We work with data from these instruments to obtain information on upper tropospheric humidity, middle and high altitude temperature. Additionally we work to improve the retrieval of ice cloud properties and development using this spectral range. Over 20 years of data help us to understand the changing climate and improve the assimilation of data in weather models.

Far-Infrared sounding.

The retrieval of atmospheric data using instruments in the far-infrared (FIR) range is another branch in our work. We work with retrievals using this range to understand the role of the FIR for the atmospheric radiation budget and tropospheric heating and cooling rates. This is related to data from REFIR-PAD and we continue supporting the missions FORUM (see the link http://clarreo.larc.nasa.gov/2011-05CLARREO_SDT_Files/Wednesday%20Presentations/Brindley_FORUM_Luca%20Palchetti.pdf, for a short description of the FORUM concept).
