Ground-Based Microwave Radiometer Measurements
This particular site and time of year was chosen by ARM because it offers a high probability of clearsky, and also a wide range of integrated water vapor amounts. To supplement the routine observing capabilities during the WVIOP2000, a powerful array of tools for measuring water vapor was deployed at the SGP Central Facility area. A comprehensive suite of airborne in situ and ground-based remote
متن کاملPerformance and application of a multi-wavelength, ground-based microwave radiometer in intense convective weather
Thermodynamic and dynamic quantities, such as the K-index and GUSTEX (a wind gust estimate), are commonly used in the nowcasting of intense convective weather. In the past, they were derived from conventional upper-air ascent measurements, which were normally only available twice a day. In the tropics, the thermodynamic property of the troposphere could change rapidly in rain episodes and the c...
متن کاملNowcasting of convective cells over Italian Peninsula
The aim of the study is the individuation of convective cells over the Italian peninsula with the conjunction use of geostationary satellite data (METEOSAT, MSG satellite) in the IR and WV channels and lightning data. We will use GCD (Global Convective Diagnostic) algorithm developed at Aviation Weather Centre (AWC) of NOAA (National Oceanic and Atmospheric Administration). This algorithm is ba...
متن کاملApplication of ground-based, multi-channel microwave radiometer in the nowcasting of intense convective weather through instability indices of the atmosphere
A ground-based microwave radiometer gives the possibility of providing continuously available temperature and humidity profiles of the troposphere, from which instability indices of the atmosphere could be derived. This paper studies the possibility of correlating the radiometer-based instability indices with the occurrence of intense convective activity, namely, the occurrence of lightning. Th...
متن کاملReprint 890 Application of a Ground-based Microwave Radiometer in Cloud Observations
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...
