public class hrptingest
The hrptingest
program converts the
high-resolution radiometer sensor data in a NOAA HRPT or CMA CHRPT
raw capture station data file into calibrated, earth-located data
in HDF or NetCDF.

The hrptingest
program converts the
high-resolution radiometer sensor data in a NOAA HRPT or CMA
CHRPT raw capture station data file into calibrated,
earth-located data in HDF or NetCDF. Currently, only NOAA KLM
and CMA FY1 satellites are supported, including NOAA-15, -16,
-17, -18, -19, and FY-1D. AVHRR or MVISR sensor data is
quality checked and re-calibrated every 5 lines. In some
cases the output data may contain missing scan lines where the
corresponding telemetry frame data was corrupt. The output
HDF or NetCDF file contains all AVHRR or MVISR channels
calibrated to scientific units, as well as earth locations and
ancilliary angles. See the various TelemetryStream
classes for descriptions of the input formats, and the CWHDFDataWriter
and CWNCDataWriter
classes for the
output format.
