Soil Moisture Experiment 2003 (SMEX03) was the second in a series of field campaigns using the National Oceanic and Atmospheric Administration Polarimetric Scanning Radiometer (PSR/CX) designed to validate brightness temperature (TB) data and soil moisture retrieval algorithms for the Advanced Microwave Scanning Radiometer (AMSR-E) for the Earth Observing(More)
The NASA Cold-land Processes Field Experiment-1 (CLPX-1) involved several instruments in order to acquire data a t different spatial resolutions. Indeed, one of the main tasks of CLPX-1 was to explore scaling issues associated with microwave remote sensing of snowpacks. To achieve this task, microwave brightness temperatures collected at 18.7, 36.5, and 89(More)
This paper describes the airborne data collected during the 2002 and 2003 Cold Land Processes Experiment (CLPX). These data include gamma radiation observations, multiand hyperspectral optical imaging, optical altimetry, and passive and active microwave observations of the test areas. The gamma observations were collected with the NOAA/National Weather(More)
During June–July 1999, the NOAA R/V Ron H. Brown (RHB) sailed from Australia to the Republic of Nauru where the Department of Energy’s Atmospheric Radiation Measurement (ARM) Program operates a long-term climate observing station. During July, when the RHB was in close proximity to the island of Nauru, detailed comparisons of shipand island-based(More)
We present a detailed analysis of the airborne passive microwave remote-sensing data that were collected at a broad range of microwave bands and at a high spatial resolution during the 2002 and 2003 National Aeronautics and Space Administration Cold Land Processes Experiment (CLPX). An accurate measurement of snowpack properties using passive microwave(More)
Anthropgenic interference from terrestrial sources of microwave emission have been observed in passive Cband radiometric data using both the NOAA Environmental Technology Laboratory’s (ETL) PSR/CX airborne imaging instrument, and the JAXA AMSR-E instrument on the NASA EOS Aqua satellite. Simultaneous observations using multiple ~300 MHz subbands,(More)
An unresolved issue in global soil moisture retrieval using passive microwave sensors is the spatial integration of heterogeneous landscape features to the nominal 50 km footprint observed by most satellite systems. One of the objectives of the Soil Moisture Experiments 2004 (SMEX04) was to address some aspects of this problem, specifically variability(More)
The retrieval algorithm was provided by the International TOVS Processing Package (ITPP). In this ITPP method, all first-guess profiles are based on statistical regression analysis. Stankov et al. (1993a) also demonstrated that accurate profiles of humidity and liquid water density can be obtained during cloudy conditions by combining data from ground-based(More)
