| Summary: | (BTs) by statistical regression onto collocated Radiosonde 0.6 g/CM2 root mean square error. The model explains 80% of the variance. A radiative transfer model applied to about 10% of the variance. Given the resultant 80-85% and show more detailed features in the PW fields, but they are overly sensitive to calibration data sets and not easily are performed for two data sets, and two best-fit models are atmospheric vertical structures. convective-like soundings. cannot anticipate the occurrence of erroneous estimations. channels and partly because of the climate changes during the chosen. Each model is dominated by different predictors, component analyses are performed on TOVS channel BTs and RAOB dry regions and underestimating in wet regions. Principal enhanced models which also include Outgoing Longwave method approaches the lower limit accuracy of microwave model is biased toward the climate mean PW, overestimating in model is developed from the calibration data set for winters Observations (RAOBs). All basic models which use only TOVS observations explain about 75% of the variance. All OLR- of 1982-1990. The model explains 74% of the variance with partly because of the high correlations between TOVS- Precipitable water (PW) is retrieved over the tropical and Radiation (OLR) as a stratification criterion explain about RAOB soundings shows that collocation errors may explain Sounder (TOVS) infrared and microwave brightness temperatures stationary variance better than transient variance. The structures for both good and poor estimations so that one subtropical Pacific Ocean from TIROS-N Operational Vertical techniques. All OLR-enhanced models capture more variance temperatures and analyze errors. The model errors and RAOB temperatures and dew point temperatures to analyze errors. The model errors are associated with certain atmospheric time period. For climatological study of PW, a comprehensive TOVS convective-like soundings. TOVS BTs have similar transportable to other time periods. Independent regressions variance explained by all basic models, the statistical vertical structures. Wet errors are associated with trade wind inversions, while dry errors are associated with more |
