AATS Team Contribution To The SAFARI 2000 Experiment


OBJECTIVES:

(1) Climate/Radiation Science : Improve understanding of smoke, haze, thin cloud, water vapor and ozone effects on the radiation budget and climate of Southern Africa and its surroundings.

(2) Satellite Validation : Test and improve the ability of satellite and A/C remote sensors to measure these constituents and their radiative effects.

- EOS Terra MODIS, MISR
- TOMS
- ER-2 MAS, AirMISR

(3) Atmospheric Correction : Investigate effects of aerosols, H 2 O, O 3 on remote measurements of surface ecosystems, ocean color, and associated biogeochemical processes.

 

INVESTIGATIONS, APPLICATIONS:

(1) Use realtime / quick-look AOD(l), column H 2 O , O 3 in flight direction and planning.

(2) Cal/Val studies for AOD(l), column H 2 O, O 3 measurements by:

- EOS Terra MODIS, MISR
- TOMS
- ER-2 MAS, AirMISR

In cases of disagreement, investigate causes and retrieval algorithm improvements.

(3) Combine our data with in situ measurements of aerosol chemical composition, size distribution, hygroscopic growth, and single-scattering albedo. Provide tests of closure and integrated assessments of aerosol and trace gas radiative effects.

(4) Combine our data with those from Peter Pilewskie's SSFR and conduct new analyses of aerosol radiative forcing sensitivity, single scattering albedo, and the solar spectral radiative energy budget.

(5) Investigate effects of aerosols, H 2 O, O 3 on remote measurements of surface ecosystems, ocean color, and associated biogeochemical processes.
