There are several options to download TAMSAT rainfall and soil moisture estimates:<\/h3>\n

[\/vc_column_text][\/vc_column][\/vc_row][vc_row css=”.vc_custom_1708361420421{margin-right: 50px !important;margin-left: 50px !important;}”][vc_column][vc_btn title=”Time and area subsetting tool<\/b>

Extract either (1) time series (CSV)<\/strong> for a specific location or area average, or (2) a gridded spatial subset (netCDF)<\/strong> from January 1983 to present. This tool is intended for time-series analysis and is not recommended for large gridded downloads over the full time period<\/strong>. For these, please use the zipped or reduced-resolution datasets below.<\/p>\n

Please note that seasonal values are rolling 3-monthly totals (for rainfall) or means (for soil moisture) which are updated monthly. As such, outputs are provided at a 1-month timestep, with each timestep corresponding to the final month of the 3-month period.<\/p>\n

[\/vc_column_text][\/vc_column][\/vc_row][vc_row css=”.vc_custom_1708361420421{margin-right: 50px !important;margin-left: 50px !important;}”][vc_column width=”1\/2″][vc_btn title=”Individual file quicklook and download<\/b>

Download individual rainfall files (netCDF format at\u00a00.0375\u00b0 resolution) and accompanying quicklook files (png format). This is useful if you want to look at rainfall estimates for a single event or over a short time-period.<\/p>\n

Download individual soil moisture files (netCDF format at\u00a00.25\u00b0 resolution) and accompanying quicklook files (png format). This is useful if you want to look at agricultural drought conditions at given point in time.<\/p>\n

[\/vc_column_text][\/vc_column][\/vc_row][vc_row css=”.vc_custom_1708361420421{margin-right: 50px !important;margin-left: 50px !important;}”][vc_column width=”1\/2″][vc_btn title=”HTTP file listing<\/b>(rainfall)” shape=”round” color=”primary” size=”lg” align=”center” link=”url:http%3A%2F%2Fgws-access.jasmin.ac.uk%2Fpublic%2Ftamsat%2Frfe%2Fdata%2Fv3.1%2F|target:_blank” css=”.vc_custom_1772107559783{margin-bottom: -10px !important;}”][vc_column_text]<\/p>\n

Download individual rainfall files (1983-present) using HTTP file listing. This can be used with tools such as wget<\/a> to download multiple files.<\/p>\n

[\/vc_column_text][\/vc_column][\/vc_row][vc_row css=”.vc_custom_1708361420421{margin-right: 50px !important;margin-left: 50px !important;}”][vc_column][vc_btn title=”Zipped file by year<\/b> (rainfall)” shape=”round” color=”primary” size=”lg” align=”center” link=”url:http%3A%2F%2Fgws-access.jasmin.ac.uk%2Fpublic%2Ftamsat%2Frfe%2Fdata_zipped%2Fv3.1%2F|target:_blank” css=”.vc_custom_1772107012654{margin-bottom: -10px !important;}”][vc_column_text]<\/p>\n

Rainfall estimates for a given time-step and year compressed into a single zip file.\u00a0This is useful if you need to download multiple files at once. If you need to download\u00a0the entire archive, we suggest using a download utility such as wget. An example (bash shell) script to download the entire archive can be found here<\/a>.<\/p>\n

[\/vc_column_text][\/vc_column][\/vc_row][vc_row css=”.vc_custom_1708361420421{margin-right: 50px !important;margin-left: 50px !important;}”][vc_column][vc_btn title=”Regridded files<\/b>(rainfall)” shape=”round” color=”primary” size=”lg” align=”center” link=”url:https%3A%2F%2Fresearch.reading.ac.uk%2Ftamsat%2Fregridded-files%2F|title:Regridded%20files|target:_blank” css=”.vc_custom_1772107584859{margin-bottom: -10px !important;}”][vc_column_text]<\/p>\n

Rainfall estimates\u00a0interpolated to a common grid (0.25\u00b0, 0.5\u00b0 and 1.0\u00b0).\u00a0These regridded files enable users to handle the data with greater ease. Interpolation has been carried out using the robust interpolation package within cf-python<\/a>.<\/p>\n

User-relevant drought and excess rainfall metrics derived from TAMSAT rainfall estimates (netCDF and accompanying PNG quicklooks).\u00a0We have recently begun releasing user-relevant metrics that can support with the monitoring of drought and excess rainfall conditions. We are still developing these products, so the current version may be updated. Eventually, these metrics will be generated for the full TAMSAT record.<\/p>\n
