The ATOVS and AVHRR Pre-processing Package (AAPP) is supplied and maintained
by the NWP SAF.
This package processes data from instruments on board the NOAA polar
orbiting satellites - namely HIRS, AVHRR, AMSU and MHS on the current
generation of satellites. It also processes data from HIRS, AVHRR, AMSU, MHS
and IASI on the European METOP satellites.
As its main output, AAPP produces files of quality-controlled
brightness temperature or radiance data for each instrument
- either separately or mapped to a common field of view.
If profiles of atmospheric variables are required the AAPP
can be used in conjunction with an inversion
package. AAPP radiance data are also used directly
as input to variational
data assimilation systems at several leading centres
for Numerical Weather Prediction.
AAPP development is closely linked to the activities and
recommendations of the International TOVS Working Group (ITWG).
The AAPP is freely available by licence, and distributed by
the Met Office. See the link at
the bottom of the page for instructions on how to request a
copy of the AAPP.
