| Summary: | Accurate retrievals of
land surface temperature (LST) from space are of high interest for studies of
land surface processes. Here, an operationally applicable method to retrieve
LST from NOAA/AVHRR data is proposed, which combines a split-window technique (SWT)
for atmospheric correction with a Normalised Difference Vegetation Index
threshold method for the retrieval of land surface emissivity. Preliminary
results of LST retrievals with this "combined method" are in good
agreement with ground truth measurements for bare soil and wheat crops. The
results are also compared with results from the same SWT but using emissivities
from laboratory measurements.<br><br><b>Key words. </b>Meteorology and
