The High Resolution Dynamics Limb Sounder (HIRDLS) instrument provides measurements of temperature, trace constituents and aerosols from the middle troposphere to the mesosphere, with a key attribute of high vertical resolution. HIRDLS will also provide key measurements of atmospheric aerosols and cirrus clouds, as well as unique measurements of sub-visible cirrus.
Validation of HIRDLS temperature retrievals demonstrate HIRDLS's ability to support Aura Science goals. Read more (pre-print)
HIRDLS detects PSCs, cirrus layers and opaque clouds. The distributions of time averaged cloud statistics compare well to correlative data. Read more (pre-print)
HIRDLS is capable of resolving fine vertical ozone features (1-2km) in the region between 1-50hPa. Read more (pre-print)
HIRDLS obtains 5000-7000 HNO3 profiles/day. HIRDLS HNO3 are generally good over 64°S-80°N and 100-10hPa, with precision between 10-15%. Read more (pre-print)
HIRDLS high resolution measurements allows analysis of a wider range of wave vertical and horizontal wavelengths than previous studies. Read more (pre-print)
