5.3.1 Data Processing
Auxiliary data:
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:
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
instrument.
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
O3, H2O,
HNO3, CH4, and
N2O and variance / covariance
matrices for the retrieved profile data.
Measurement data:
Measurement data are all processed observational data and auxiliary data delivered
by the instrument to the PPF Data Handling
Assembly.
Observational data:
Observational data are all
raw sensor data acquired by the instrument after
digitization.
