I would like to download precipitation data from satellite precipitation products, is it possible please to suggest me the most frequently products that are used and recommended for hydrological studies.
Is it possible to give me the links to download numerical data or some scripts to download them from programming tools like Matlab ou python.
Thank you.
Dear Myriam Benkirane ,
I suggest you try with the following satellite precipitation data sets
Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks (PERSIANN), PERSIANN-Cloud Classification System (PERSIANN-CCS), PERSIANN-Climate Data Record (PERSIANN-CDR), Tropical Rainfall Measuring Mission (TRMM-3B42-V7), TRMM Multi satellite Precipitation Analysis Real Time (TMPA-RT) and Integrated Multi-satellite Retrievals from GPM (IMERG)
Hi Myriam Benkirane
More information on satellite-based precipitation datasets can be found at http://ipwg.isac.cnr.it/
The choice of the SPPs depends on many factors, including:
-The end goal of your work (e.g., floods, droughts, near real time predictions, historical simulations, high vs. low resolution requirements in time and space, etc.)
-Your study area and period (e.g., basin size, climate, location, period of study, etc.)
-Computational facilities: you might go for high resolution (time and space) data if you have the means to store and use the data.
-Some datasets are not available in "classic" formats (e.g. tiff or netcdf), therefore you might have to do some pre-processing work which is not always straightforward.
Based on these factors and probably many others, you might find studies that have already evaluated and compared the SPPs in your region, or a region with similar features.

Dear All,
Thank you so much for answering my question.
Have a nice day,
