The data set includes multi-satellite averages, inter-sensor calibration, and an efficient sea ice detection procedure. Changes in this version are a prolonged time series, now containing data from 1987 to 2005, a new neural network based precipitation algorithm, and inclusion of the RSMAS/NODC Pathfinder Version 5 SST fields. Additionally a new 85 GHz synthesis procedure has been implemented for the time period to compensate for the missing channel information on DMSP F08, see accuracy report.[[BR]] Apart from monthly and pentad (5-day) means on a global 0.5 deg. x 0.5 deg. grid, twice daily multi-satellite composite data on a global 1 x 1 grid are available. Access: You will find the datasets in the CERA database: http://cera-www.dkrz.de/WDCC/ui/Compact.jsp?acronym=HOAPS3_MONTHLY To get data, you have to get an account as described here: https://cera-www.dkrz.de/WDCC/ui/Login.jsp Then you can add datasets to your process list and download the data.
