PPS has created a new PPS/GPM Science Algorithm Toolkit (TKIO) package which includes all the latest production formats. Those wishing to access new production data products listed below using C and Fortran interfaces may wish to download this TKIO package. Those using development TKIO versions that include the newer products do not need this public distribution, it is optional. 

This 3.97 TKIO includes all production formats including the recent additions of the V06X radar products and 3B42/3 in HDF5.
