| Zusammenfassung |
| The geopotential height (GPH) product created from global observations by
the High Resolution Dynamics Limb Sounder (HIRDLS) instrument on NASA's
Earth Observing System (EOS) Aura spacecraft is discussed. The accuracy,
resolution and precision of the HIRDLS version 7 algorithms are assessed and
data screening recommendations are made. Comparisons with GPH from
observations, reanalyses and models including European Centre for
Medium-Range Weather Forecasts Interim Reanalysis (ERA-Interim), and
National Centers for Environmental Prediction/National Center for
Atmospheric Research (NCEP/NCAR) Reanalysis illustrate the HIRDLS GPHs have a
precision ranging from 2 to 30 m and an accuracy of ±100 m up to 1 hPa.
Comparisons indicate HIRDLS GPH may have a slight low bias in the tropics
and a slight high bias at high latitudes. Geostrophic winds computed with
HIRDLS GPH qualitatively agree with winds from other data sources including
ERA-Interim. |
