Our Climate Variability and Change Analysis Group analyzes data on
daily to multi-decadal atmospheric variations measured by many types of
observing systems. Our specialty is working with radiosonde (weather
balloon) data. Through our radiosonde research, we have identified
important data problems and produced new, improved datasets. We use these
and other datasets to identify and characterize climate variability and
trends. We also work collaboratively with climate modeling groups who use
our datasets to evaluate global climate models.
