Advanced Microwave Scanning Radiometer-2 (AMSR2) is a successor of AMSR for Earth-Observation System (AMSR-E), while the third generation (AMSR3) will be launched in near future. The AMSR2 soil moisture product also an important component Soil Moisture Operational Products (SMOPS) datasets that are operationally produced by National Oceanic and Atmospheric Administration (NOAA). Refinement NOAA...

In October 2003 a campaign on board the Australian icebreaker Aurora Australis had the objective to validate standard Aqua Advanced Microwave Scanning Radiometer (AMSR-E) sea-ice products. Additionally, the satellite laser altimeter on the Ice, Cloud and land Elevation Satellite (ICESat) was in operation. To capture the large-scale information on the sea-ice conditions necessary for satellite v...

Vegetation optical depth (VOD) retrieved from microwave remote sensing techniques has been used as an important proxy for monitoring the vegetation dynamics at large scales. In a first study we developed new X-VOD indice inversion of X-MEB model Microwave Scanning Radiometer 2 (AMSR2, 2012-present) observations. The Advanced EOS (AMSR-E, 2002–2011) and AMSR2 share many characteristics, such loc...

Vertisols are clay soils that are common in the monsoonal and dry warm regions of the world. One of the characteristics of these soil types is to form deep cracks during periods of extended dry, resulting in significant variation of the soil and hydrologic properties. Understanding the influence of these varying soil properties on the hydrological behavior of the system is of considerable inter...

The heat insulation effect of sea ice is greatly reduced in thin ice area. Turbulent heat flux to the atmosphere at the thin ice surface is possibly 2 orders of magnitude larger than that at the thicker ice surface. In coastal polynya, which is mostly covered with thin ice, sea ice is formed very actively because of the large amount of heat loss to the atmosphere. Further, dense shelf water (DS...

Cloud droplet effective radius (DER) and liquid water path (LWP) are two key parameters for the quantitative assessment of cloud effects on the exchange of energy and water. Chang and Li presented an algorithm using multichannel measurements made at 3.7, 2.1, and 1.6 m to retrieve a cloud DER vertical profile for improved cloud LWP estimation. This study applies the multichannel algorithm to th...

Surface wind vector measurements over the oceans are vital for scientists and forecasters to understand the Earth's global weather and climate. In the last two decades operational measurements of global ocean wind speeds were obtained from passive microwave radiometers (SSM/I’s); and over this period, full ocean surface wind vector data were obtained from several NASA and ESA scatterometry miss...

Antarctic Sea Ice Processes and Climate (ASPeCt) ship-based ice observations, conducted during the Sea Ice Mass Balance in the Antarctic (SIMBA) and Sea Ice Physics and Ecosystem eXperiment (SIPEX) International Polar Year (IPY) cruises (September–October 2007), are used to validate remote-sensing measurements of ice extent and concentration. Observations include varied sea-ice types at and ins...

Uncertainties in model parameters can easily result in systematic differences between model states and observations, which significantly affect the accuracy of soil moisture estimation in data assimilation systems. In this research, a soil moisture assimilation scheme is developed to jointly assimilate AMSR-E (Advanced Microwave Scanning Radiometer-Earth Observing System) brightness temperature...
