Monitoring the Characteristics of Satellite Microwave Water Vapor Observations Over the Ocean
The importance of atmospheric water vapor in weather and climate processes is well understood (see for example the reports from the AGU Chapman Conferences on Atmospheric Water Vapor in 1994, 1999 and 2008). Less well understood is the accuracy and precision of moisture observations that are analyzed and assimilated into atmospheric models over ...
Web-based prototype decision support tool
NOAA ESRL has created a software tool that is aimed at exploring optimum methods for disseminating weather prediction data directly to an individual decision maker, supporting both economic and personal decisions. This includes a web interface that is connected to calibrated, probabilistic model output that allows a user to identify places and t...

Possible Solar Influences Observed in GOES and MODIS Total Precipitable Water Product Data
The NOAA Earth System Research Laboratory (ESRL) has been comparing GOES water vapor products with derived water vapor estimates from global positioning system (GPS) signal delays since 2002 (Birkenheuer and Gutman, 2005). Data from the GPS and other Global Navigation Satellite Systems (GNSS) allows us to objectively intercompare water vapor est...
We report on precipitable water vapor (PWV) from a Global Positioning System (GPS) receiver and surface meteorological network during the 2004 North American Monsoon Experiment (NAME) in northwestern Mexico. The monsoon onset is evident as a large PWV increase over several days beginning July 1. Data in the Sierra Madre Occidental (SMO) foothill...
Devised scheme to correct GOES bias in GOES operational total precipitable water products
The National Environmental Satellite Data and Information Service (NESDIS) Geostationary Observational Environmental Satellite (GOES)-derived, total precipitable water (TPW) vapor product is routinely produced at NESDIS for Advanced Weather Interactive Processing System (AWIPS) users, primarily for National Weather Service (NWS) forecast offices...

Improved GOES water vapor products over CONUS - planning for GOES-R
The NOAA Earth System Research Laboratory (ESRL) has been comparing GOES water vapor products with ground-based global positioning system (GPS) integrated water vapor estimates since 2002 (Birkenheuer and Gutman, 2005). The purpose of this work has been to assess GOES total precipitable water (TPW) retrieval performance at both synoptic and asyn...
Operational assimilation of GPS-IPW observations in the 13-km RUC at NCEP
GPS integrated precipitable water (GPS-IPW) observations are a relatively recent asynoptic data source of moisture information for data assimilation. Short-range numerical weather forecasts suffer from inadequate observational definition of the threedimensional moisture field due to its high spatial and temporal variability. Generally, there hav...

Ground-based GPS meteorology at the NOAA Forecast Systems Laboratory
Verification has been and continues to be essential to the development and operational transition of Global Science Division (GSD) models, particularly the Rapid Refresh (RAP) and the High Resolution Rapid Refresh (HRRR). To that end, the GSD Assimilation Development Branch (ADB) has developed and maintained a verification system over the past d...
Institution National Oceanic and Atmospheric Administration - NOAA
Developing and improving numerical weather prediction models such as the Rapid Refresh (RAP) and High-Resolution Rapid Refresh (HRRR) requires a well-designed, easy-to-use evaluation capability using observations. Owing to the very complex nonlinear interactions between the data assimilation system and the representation of various physics compo...

The complex interactions between water vapor fields and deep atmospheric convection remain one of the outstanding problems in tropical meteorology. The lack of high spatial–temporal resolution, all-weather observations in the tropics has hampered progress. Numerical models have difficulties, for example, in representing the shallow-to-deep conve...

The North American Monsoon GPS Transect Experiment 2013
Northwest Mexico experiences large variations in water vapor on seasonal time scales in association with the North American monsoon (NAM), as well as during the monsoon associated with upper tropospheric troughs, mesoscale convective systems, tropical easterly waves and tropical cyclones. Together these events provide more than half of the annua...
