All SSM/I, TMI, and AMSR-E data used in the climatology construction were produced by Remote Sensing Systems (available online at http://www.remss.com), with partial sponsorship from the NASA AMSR-E science team, as well as the NASA Earth Science REASoN project (Research, Education and Applications Solution Network), a distributed network of data and information providers for NASA’s Earth Science Enterprise (ESE) Science, Applications and Education Programs. Liquid water data using the Greenwald et al. (1993) algorithm were produced at the NASA Langley Research Center; liquid water paths using the W97 algorithm were produced at the National Climatic Data Center, a division of NOAA/National Environmental Satellite, Data, and Information Service (NESDIS). The ERA-40 data were obtained through the Computational Information and Systems Laboratory (CISL) at the National Center for Atmospheric Research (NCAR). Special thanks to Ralph Ferraro for help with accessing and interpreting the NOAA/NESDIS data.
