OVERVIEW

NOTE: The latent heating products of TRMM 2A12 and 3A12 over ocean surfaces should be regarded as experimental.Please confer first with the algorithm developers (by contacting the GES DISC) when using the latent heating product over ocean.Over-land latent heating estimates from TRMM products 2A12 and 3A12 should not be used, as they have not been evaluated quantitatively or qualitatively.

PDISC Guide for New Users

For users new to the PDISC, we offer a getting started guide.

Precipitation Data Services at the DISC

  • Facilitate data access, information processing to support precipitation research and decision making
  • Nurture cross disciplinary precipitation related research, such as energy and water cycle, aerosol-precipitation interactions

The data holdings at the PDISC consist of remote sensing, in-situ and forecast (to be added in the future) precipitation and ancillary data. The PDISC also provides access to near-real-time and historical precipitation data. The TRMM Online Visualization and Analysis System TOVAS provides a fast and easy way to access the most popular products. While you're here, check out:
