[1] This paper investigates the influence of cloud model statistics on the accuracy of statistical multiple‐frequency liquid water path (LWP) retrievals for a ground‐based microwave radiometer.

Statistical algorithms were developed from a radiosonde data set in which clouds were modeled by using a relative humidity threshold and a modified adiabatic assumption. Accuracy of cloud liquid water path from ground-based microwave radiometry 1.

Arctic clouds strongly influence the regional radiation balance, temperature, melting of sea ice, and freezing of sea water. Despite their importance, there is a lack of systematic and reliable observations of Arctic clouds.

In the work by Kneifel et al. [19], a significant TB enhancement in ground-based measurements at 90 and GHz is observed in presence of snowfall, due to the large amounts of liquid water and to. retrieval of atmospheric temperature profile, water vapor content, cloud liquid path, and cloud depolarization ratio.

In particular, the GHz channels are located in the strong oxygen absorption. Partnered Journals. Chinese Journal of Geophysics () Earth Interactions; Earth and Planetary Physics; Geophysics; International Journal of Geomagnetism and Aeronomy.

Introduction. Airborne and spaceborne sensors provide critical data to the scientific community for Earth-observation studies. Long-term environmental data sets are maturing and expanding with the launch of an ever-increasing number of sensors from both the government and commercial sectors. 1 Scientific models are created using sensors with a wide variety of spectral, spatial, and temporal Cited by: 6.

Targeting seedable clouds with silver iodide in complex terrain adds considerable uncertainty in weather modification studies.
