Recent changes in the NWS upperair observing network are listed and an analysis is presented of the change in 1995 from VIZ to Vaisala radiosonde instruments. Results are shown for 14 stations at 850, 700, 500, 100, and 50 hPa and atboth 0000 and 120

Annual and seasonal correlations between temperature and both specific and relative humidity are presented based on radiosonde station data over the tropical Pacific Ocean and North America. Results are presented for the surface and the 850-, 700-, a

Trends in tropospheric water vapor at Northern Hemisphere radiosonde stations are presented for two periods;1973–95 and 1958–95. Stations with incomplete or inhomogeneous temporal records were identified and excluded from the analysis. For the 19

A temporally and spatially comprehensive depiction of the tropical tropopause is presented, based on radiosonde data from 83 stations. Climatological statistics for 1961- 1990 are computed for three levels: the conventional lapse-rate tropopause (LRT

Possible changes to the North American Atmospheric Observing System that are under discussion include the scheduling of radiosonde launches according to synoptic conditions. The authors estimate biases in long-term monthly mean tropospheric temperatu

Trends in global lower tropospheric temperature derived from satellite observations since 1979 show less warming than trends based on surface meteorological observations. Independent radiosonde observations of surface and tropospheric temperatures co

Climatological annual and seasonal dewpoint, specific humidity, and relative humidity maps for the United States are presented using hourly data from 188 first-order weather stations for the period 1961‐90. Separate climatologies were calculated fo

Here 21 years of radiosonde observations from stations in the Western Hemisphere north of the equator were analyzed for trends in tropospheric water vapor. Mean fields of precipitable water and relative humidity at several levels we shown. Annual tre
