Developments in the assimilation of satellite data in numerical weather prediction (NWP),
from the first experiments in the late 1960s to the present day, are presented in a two‐part …

Atmospheric sounding of the vertical changes in temperature and moisture is one of the key
contributions from meteorological satellites. The concept of using satellite infrared radiation …

Recent data assimilation developments which have taken place at numerical weather‐
prediction centres are briefly discussed, from the perspectives of both the importance of data …

The influence matrix is used in ordinary least‐squares applications for monitoring statistical
multiple‐regression analyses. Concepts related to the influence matrix provide diagnostics …

Abstract The Infrared Atmospheric Sounding Interferometer (IASI) is an infrared Fourier‐
transform spectrometer that has been flying on the MetOp satellite series since October …

The first Russian advanced infrared (IR) atmospheric sounder IKFS-2 was launched in July
2014 on the “Meteor-M” No. 2 meteorological satellite. It is planned that this instrument and …

In this paper, a fast atmospheric and surface temperature retrieval algorithm is developed for
