Precipitation and OLR Data

Global Precipitation Climatology Project (GPCP)

The Global Precipitation Climatology Project (GPCP) was established by the World Climate Research Program (WCRP) to address the problem of quantifying the distribution of precipitation around the globe over many years. The general approach is to combine the precipitation information available from each of several sources into a final merged product, taking advantage of the strengths of each data type.

The data set archive consists of yearly unformatted REAL*4 binary files with ASCII headers, each of which holds 12 monthly fields. Each file occupies almost 0.5 MB. The grid on which each field of values is presented is a 2.5°x2.5° latitude–longitude (Cylindrical Equal Distance) global array of points. It is size 144×72, with X (longitude) incrementing most rapidly West to East from the Prime Meridian, and then Y (latitude) incrementing North to South. Grid edges are placed on whole- and half-degree values:

First point center = (88.75°N,1.25°E)
Second point center = (88.75°N,3.75°E)
Last point center = (88.75°S,1.25°W)

Missing values are denoted by the value -99999., and the units on the fields depend on the variable. For example, rainfall is carried as mm/day.

 Tropical Rainfall Measurement Mission (TRMM)

The Tropical Rainfall Measurement Mission (TRMM) is being flown by the National Aeronautics and Space Administration (NASA, U.S.) and the Japan Aerospace Exploration Agency (JAXA, Japan) to improve our quantitative knowledge of the 3-dimensional distribution of precipitation in the tropics. TRMM has a passive microwave radiometer (TRMM Microwave Imager, TMI), the first active space-borne Precipitation Radar (PR), a Visible-Infrared Scanner (VIRS), and other instruments. Coordinated observations are intended to result in a “flying raingauge” capability.

The data set archive consists of binary data sets in Hierarchical Data Format (HDF). Each 3B42 file contains a 3-hourly estimate and each 3B43 file contains a one-month estimate. The grid on which each field of values is presented is a 0.25 deg x 0.25 deg latitude–longitude (Cylindrical Equal Distance) array of points over the latitude range 50N-S. It is size 400×1440, with X (latitude) incrementing most rapidly South to North, and then Y (longitude) incrementing West to East from the Date Line. Grid edges are located at whole-degree values:

First point center      = (49.875S,179.875W)
Second point center = (49.625S,179.625W)
Last point center      = (49.875N,179.875E)

Missing values are denoted by the value -9999.9, and the units are mm/hour.

Outgoing Longwave Radiation (OLR)

Uninterpolated and Interpolated gridded data are obtained from NOAA/OAR/ESRL/PSD
Temporal Coverage:

(from twice daily Advanced Very High Resolution Radiometer (AVHRR) soundings for OLR)
