| Zusammenfassung |
| The mid-infrared solar absorption FTIR instruments of the Network of the Detection of
Atmospheric Composition Change (NDACC) provide the hitherto unused possibility to
retrieve trends of atmospheric water vapor. Measurements at more than a dozen of NDACC
FTIR sites around the globe cover meanwhile a time span of more than 1 decade. We have
shown recently that trends in integrated water vapor can be retrieved from these existing
long-time measurement series with unprecedented accuracy and precision (Sussmann et al.,
2009).
The presentation details the strategy for harmonized retrieval of integrated water vapor
from routine FTIR measurements at the different NDACC stations. The retrieved trends will
be discussed in terms of statistical significance.
The paper gives also first results on the correlation of integrated water vapor trends
with co-located surface temperature trends. The study shows an unexpected riddle
of correlation versus non-correlation. Possible geophysical explanations will be
discussed.
