Impact of Vaisala Radiosonde Humidity Corrections on ARM IOP Data
Radiosonde humidity measurements are fundamentally important to a variety of applications, including radiative transfer calculations, validation of remote-sensor retrievals, parameterization of cloud processes, and initialization of (or assimilation into) numerical models. Vaisala radiosondes, used by the Atmospheric Radiation Measurement (ARM) Program and extensively throughout the world, are ...
متن کاملTropical thin cirrus and relative humidity observed by the Atmospheric Infrared Sounder
Global observations of cloud and humidity distributions in the upper troposphere within all geophysical conditions are critically important in order to monitor the present climate and to provide necessary data for validation of climate models to project future climate change. Towards this end, tropical oceanic distributions of thin cirrus optical depth (τ ), effective diameter (De), and relativ...
متن کاملCO2 retrievals from the Atmospheric Infrared Sounder: Methodology and validation
[2] Although it was designed for high resolution/accurate temperature and moisture profiles, the National Aeronautics and Space Administration Earth-Observing System (NASAEOS) Atmospheric Infrared Sounder (AIRS) is capable of measuring variations in carbon trace gases such as CO2 [Chédin et al., 2003; Crevoisier et al., 2003; Engelen and Stephens, 2004; Aumann et al., 2005]. This capability cou...
متن کاملComparison of upper tropospheric water vapor observations from theMicrowave Limb Sounder and Atmospheric Infrared Sounder
[1] We compare matched retrievals of upper tropospheric water vapor (UTWV) mixing ratios from the Microwave Limb Sounder (MLS) instrument on the Aura satellite, and the Atmospheric Infrared Sounder (AIRS) instrument on the Aqua satellite. Because each instrument’s sampling is affected by tropical conditions, about half of mutually observed scenes in the tropics yield simultaneous successful ret...
متن کاملStudy on Hyper-spectral Atmospheric Infrared Sounder Assimilation
Hyper-spectral Atmospheric Infrared Sounder has many channels. Although, it has been carried out channel selection in the actual application process, but compared with the previous detector, the channel also seems more and thus easy to weak correlation between channels, which is not obey classical variational assimilation theory requires observation error is not related. Hyper-spectral sounder ...
