Is there a program or routine within a program to validate rainfall data on weather grids and satellites or gridded data? To cite example the satellite Global Precipitation Climatology Centre - GPC or TRMM.
I want to compare and validate data from physical rainfall stations with data from weather satellites.
Dear Ferreira Filho, this type of procedure is usually done through statistical software such as Excel or R. To do this just follow the performance statistics widely discussed in the literature, such as: Nash-Sutcliffe, Willmott's concordance index, Determination Coefficient and Pearson's correlation among others ...
Yes, the tests mentioned above are already to my knowledge, I should practice them more in R. Thanks.
Dear David Ferreira Filho, are you looking for a way to extract data from a certain product (GPCC, TRMM or other) near the surface stations? This procedure is simple. I search the product data based on the coordinates of the weather station, from a procedure performed by R. If you are interested, we can talk about it.
