A new type of microwave radiometer detector has been developed that is capable of identifying low level Radio Frequency Interference (RFI) and of reducing or eliminating its effect on the measured brightness temperature. The Agile Digital Detector (ADD) can discriminate between RFI and natural thermal emission signals by directly measuring other moments of the signal than the variance that is t...

Considerable research efforts have been made to detect and understand the variations in the entire spectral band and in the near-UV, visible and infrared spectral bands since the SOLERS22 1991. Workshop. Besides the ERB on NIMBUS7 and the ERBE experiments on ERBS, NOAA9 and NOAA1O satellites, additional space experiments provided data for total irradiance. The ACRIM 11 radiometer on board the U...

A neural network-based retrieval technique is developed to infer vapor, liquid. and ice columns using twoand threechannel microwave radiometers. Neural network-based inverse scattering methods are capable of merging various data streams in order to retrieve microphysical properties of clouds and precipitation. The method is calibrated using National Oceanic and Atmospheric Administration (NOAA)...

With the advent of the microwave radiometer, passive remote sensing of clouds and precipitation has become an indispensable tool in a variety of meteorological and oceanographical applications. There is wide interest in the quantitative retrieval of water vapor, cloud liquid, and ice using brightness temperature observations in scientific studies such as earth’s radiation budget and microphysic...

A method is presented for inferring both the size distribution and the complex refractive index of atmospheric particulates from combined bistatic-monostatic lidar and solar radiometer observations. The basic input measurements are spectral optical depths at several visible and near-infrared wavelengths as obtained with a solar radiometer and backscatter and angular scatter coefficients as obta...

Measurement of lactate levels is important in the care of critically ill adult and pediatric patients. We compared 3 whole blood lactate methods (Radiometer ABL 725, Radiometer Medical A/S, Bronshoj, Denmark; i-STAT, i-STAT, East Windsor, NJ; and Nova Lactate Plus, Nova Biomedical, Waltham, MA) with 2 plasma-based methods (Roche Integra, Roche Diagnostics, Indianapolis, IN; and Vitros, Ortho Cl...

The use of cloud-base height data obtained from a groundbased microwave radiometer in the estimation of total cloud amount has been studied by Chan and Li (2009). The present paper extends the study by considering the performance of the total cloud amount estimation algorithm in different seasons and different years. It is found that the algorithm works generally well in different periods by co...
