java.lang.Objectterrenus.instrument.AbstractRadiometerDataWriter
terrenus.instrument.CWNCDataWriter
public class CWNCDataWriter
The CWNCDataWriter
class writes radiometer data
to netCDF version 3 files. All available radiometer channels
are written in units specified by the AbstractRadiometerDataWriter.writeData(terrenus.telemetry.TelemetryDecoder, terrenus.instrument.Radiometer, int, int, terrenus.instrument.RadiometerCalibrator.CalibrationType, terrenus.instrument.RadiometerCalibrator.CalibrationType)
method. The metadata written conforms to the CoastWatch HDF
version 3.4 specificaion. Latitude, longitude, satellite
zenith, solar zenith, and relative azimuth data are also
computed and written in degrees. Latitude and longitude
variables are written as netCDF 32-bit floats, and all other
angle data and radiometer channels as netCDF 16-bit signed
integers scaled by 0.01.
