A calibration facility for automatic weather stations

Some General Considerations and Specific Examples in the Design of Algorithms for Synoptic Automatic Weather Stations

 A novel approach to automatic position calibration for pixelated crystals in gamma imaging

Introduction: The position estimation in gamma detection system will have constant misplacements which can be corrected in the calibration procedure. In the pixelated crystal uniformly irradiation of detector will produce irregular shape due to position estimation errors. This image is called flood field image and is used to calibrate the position estimation. In this work we pr...

Discrimination Calibration Analysis Methods for Regional Stations

For event discrimination, operational implementation of a regional seismic station requires three sequential calibration analyses. 1) Magnitude, distance, and amplitude corrections (MDAC) made to observed regional amplitudes are necessary so that what remains in the corrected amplitude is mostly information about the seismic source-type. Corrected amplitudes can be used in ratios to discriminat...

Microclimate Exposures of Surface-based Weather Stations

APRIL 2005 AMERICAN METEOROLOGICAL SOCIETY | T he U.S. Historical Climate Network (USHCN; Karl et al. 1990) consists of a subset of stations from the National Weather Service (NWS) cooperative (COOP) station network. The USHCN stations are used in the construction of homogeneous climate data reference series and in the detection and monitoring of long-term climatic trends. Stations are selected...

Network Architecture for Small X-band Weather Radars – Test Bed for Automatic Inter-calibration and Nowcasting

In recent years the use of small inexpensive Xband radars for meteorological and hydrological purposes has increased significantly. Compared to the traditional C-band and S-band radars the X-band weather radar has the advantage of high temporal and spatial resolution and low financial cost; however, the trade off is attenuation due to X-band technology and short range due to the higher spatial ...
