Measurements and Observations at Aeronautical Meteorological Stations

ثبت نشده
چکیده

This chapter deals with the requirements for observations at aeronautical meteorological stations and the instruments and methods that are used. Synoptic observations measure at one location a representative value for a rather large area, but meteorological observations for aeronautical purposes are often made at several locations at the aerodrome and in the surrounding area, at more frequent intervals, to be representative of rather limited areas, such as the approach, touchdown and take -off areas.

The Chinese observed land-surface air temperature data set includes measurements from 731 meteorological stations from 1951 to the present, as collected and processed by the National Meteorological Center of the China Meteorological Administration (1, 2). Because some stations were removed, the actual total number of stations in operation today is 671, distributed among 31 provinces and municip...

Spatial Interpolation of High - Frequency Monitoring Data

Climate modelers generally require meteorological information on regular grids, but monitoring stations are, in practice, sited irregularly. Thus, there is a need to produce public data records that interpolate available data to a high density grid, which can then be used to generate meteorological maps at a broad range of spatial and temporal scales. In addition to point predictions, quantific...

Decadal variations in atmospheric water vapor time series estimated using ground-based GNSS

Ground-based GNSS (Global Navigation Satellite Systems) have efficiently been used since the 1990s as a meteorological observing system. Recently scientists used GNSS time series of precipitable water vapor (PWV) for climate research. In this work, we use time series from GNSS, European Center for Medium-Range Weather Forecasts Reanalysis (ERA-Interim) data, and meteorological measurements to e...

Hail detection methods using radar data

Different methods for hail detection are presented in the seminar. The presented methods use radar reflectivity measurements to determine the occurrence of hail. We compared observations made on meteorological stations, radar derived product developed by Faculty of mathematics and physics (FMF) and radar derived product VIL (Vertically integrated liquid). Comparison is performed for the period ...
