Instrumentation Platform
A. Top-of-Atmosphere Radiation (W. Collins, J. Coakley, V. Ramanathan, C. Weaver)

1) AVHRR: NOAA-12, 14, K 5-channel narrow-band visible and infrared radiance images with LAC (1 x 1 km2) resolution twice daily per satellite; central wave numbers are 0.6­0.7 µm, 0.7­1.0 µm, 1.6 µm (NOAA-K), 3.5­4.0 µm (NOAA-12,14), 10.3­11.3 µm, and 11.5­12.5 µm Source: SeaSpace receiving systems operated by C4 (primary)

NOAA-12, 14, K
2) VHRR: 2-channel narrow-band visible and infrared radiance INDOEX sector images with INSAT (2.75 km)2 (vis) and (11.0 km)2 (IR) resolution every hour; central wave numbers are 0.5­0.75 µm and 10.5­12.5 µm Source: ISRO These data will be used to derive cloud parameters and structure, the distribution and diurnal cycle of convective complexes, and aerosol optical depth

B. Remote Infrared Soundings (N. Scott, LMD) TOVS: High-resolution sounder with 19 narrow-band NOAA-12, 14, K channels in the near and mid-IR spectrum with resolution ranging from 18 km2 (nadir) to 58 km x 29 km (end of scan). These data will be used to derive temperature and humidity vertical profiles, clouds and surface characteristics, vertical and spectral distributions of radiation budget (3I Algortithm)

NOAA-12, 14, K
C. Water Vapor from Microwave Imaging (PI: N/A) SSM/I-2: Column-integrated water vapor and DMSP F-10, 11 precipitation rates at 60 x 40 km2 (nadir) resolution twice daily from the Defense Meteorological Satellite Program (DMSP) special sensor microwave imager; presumed accuracy is 10­15%

DMSP F-10, 11
