A new service converting Level-3 TRMM_3B43 data in HDF4 format into netCDF format is now available through Mirador. The service uses a GrADS tool lats4d for data format conversion. The conversion is done "on-the-fly" when a user elects to download Level-3 TRMM_3B43 data in netCDF format from Mirador.
To use the service, drill down to data from the following link and use the "NetCDF" link.
