| 104 | Documentation: |
| 105 | The Hamburg Ocean Atmosphere Parameters and Fluxes from Satellite Data (HOAPS) set is a completely satellite based climatology of precipitation, evaporation and freshwater budget (evaporation minus precipitation) as well as related turbulent heat fluxes and atmospheric state variables over the global ice free oceans.[[BR]] |
| 106 | All variables are derived from SSM/I passive microwave radiometers, except for the SST, which is taken from AVHRR measurements. The data set includes multi-satellite averages, inter-sensor calibration, and an efficient sea ice detection procedure. |
| 107 | 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]] |
| 108 | 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. |
| 109 | |
| 110 | Access: |
| 111 | You will find the datasets in the CERA database: |
| 112 | http://cera-www.dkrz.de/WDCC/ui/Compact.jsp?acronym=HOAPS3_MONTHLY |
| 113 | To get data, you have to get an account as described here: |
| 114 | https://cera-www.dkrz.de/WDCC/ui/Login.jsp |
| 115 | Then you can add datasets to your process list and download the data. |
| 116 | Another possibility is to use the jblob command line tool: |
