Data Set Organization

TRMM

The data format is similar to original TRMM data. Please refer to TRMM Data user's handbook for Data format of TRMM Tropical Cyclones Data Set. The change of data format between Tropical Cyclones Data and original data is as follows.
  1. Parameters
    product version: V7
    product: 2A25
    Though the following five Global Attributes are newly added to 2A25 of product version 7, they are not included in the Tropical Cyclones Data.
    Parameters: General
    Parameters: Convective
    Parameters: Stratiform
    Parameters: Other
    Parameters: Errors
  2. Core meta data

    OrbitLastScanUTCTimeThe end scan time (UTC, HH:MM:SS) of Tropical Cyclones Data is set.
    OrbitLastScanUTCmillisecondsThe end scan time (UTC, msec) of Tropical Cyclones Data is set.
    CenterScanUTCTime  *1The center scan time (UTC, msec) of Tropical Cyclones Data is set.
    CenterScanUTCMillisec  *1The center scan time (UTC, msec) of Tropical Cyclones Data is set.
    NumberOfRainScans  *1The number of rain scans of Tropical Cyclones Data is set.

Tools

In order to make TRMM data visibe, PPS Orbit Viewer is excellent. It is a menu-driven graphical interface for dynamically generating images from TRMM HDF files.
The easiest way to read TRMM data in HDF format is to call the PPS ToolKit library from C or Fortran programs. Please refer to the following linked document for more details.

AMSR/AMSR-E/AMSR2

The data format is similar to original AMSR/AMSR-E/AMSR2 data. Please refer to AMSR/AMSR-E/AMSR2 Data user's handbook for Data format of AMSR/AMSR-E/ASMR2 Tropical Cyclones Data Set. The change of data format between Tropical Cyclones Data and original data is as follows.
