We demonstrate that the global fields of temperature, humidity, and geopotential heights admit a nearly sparse representation in the wavelet domain, offering a viable path forward to explore new paradigms of sparsity-promoting data assimilation and compressive recovery of land surface-atmospheric states from space. We illustrate this idea using retrieval products of the Atmospheric Infrared Sou...

[1] The hypothesis of large scale control of midlatitude water vapor is evaluated through reconstructions of the water vapor field using a Lagrangian advectioncondensation model without microphysics or diffusion. The reconstruction is validated against satellite observations in the 183.31 ± 1 GHz band from the AMSU-B radiometer following a model-to-satellite approach. Because microwave radiatio...

[1] Measurements with an airborne microwave radiometer are used to validate absorption models in clear air at frequencies used in satellite microwave humidity sounders, such as AMSU-B and MHS. The data set includes 33 profiles of radiometric and in situ observations ranging from the tropics to the high arctic. In cold, dry conditions the MPM and Rosenkranz models were found to underestimate the...

In the last years satellite remote sensing applications in hydrology have considerably progressed. A new multi-temporal satellite data-analysis approach has been recently suggested in order to estimate space-time changes of geophysical parameters possibly related to the increase of environmental and hydro-geological hazards. Such an approach has been already used both for flooded area mapping (...

Abstract. To advance our understanding of the stratosphere, high-quality observational datasets stratosphere are needed. It is commonplace that reanalysis used to conduct stratospheric studies. However, accuracy these reanalyses at heights hard infer due a lack in situ measurements. Satellite measurements provide one source temperature information. As some satellite information already assimila...
