5.3.1 Data Processing
Auxiliary data are all data to be provided by an
instrument or an external source to allow full
interpretation and evaluation of its observational data.
Coaddition is synonym of averaging.
Level 0 data:
MIPAS Level 0 data is a raw interferogram
with corresponding ancillary data. Level 0 data
typically covers one complete orbit
corresponding to a data stream of about 100
minutes. Level 0 data comes directly from the
Level 1a data:
MIPAS Level 1a data is an intermediary data set.
It consists of reconstructed interferograms.
Level 1 a data are not archived.
Level 1b data:
MIPAS Level 1b data is a radiance spectrum that
is geolocated, radiometrically calibrated,
spectrally calibrated, corrected for spike,
corrected for non-linearity and fringe count
errors, and annotated with quality indicators.
Level 2 data:
MIPAS Level 2 data include geolocated
geophysical parameters retrieved from the
atmospheric radiance spectra. Level 2 data
includes: atmospheric pressure at tangent
altitudes, kinetic temperature, tangent height
correction, volume mixing ratio of
HNO3, CH4, and
N2O and variance / covariance
matrices for the retrieved profile data.
Measurement data are all processed observational data and auxiliary data delivered
by the instrument to the PPF Data Handling
Observational data are all
raw sensor data acquired by the instrument after
