Hello!! It's Joseph

The trouble stemmed from a motor vibration , which caused a lubricant buildup that obstructed the spinning motion of the filter wheel in the sounder . A team of engineers from NOAA, Boeing and ITT suppressed the vibration, the filter wheel restarted and is running smoothly, with improved performance The GOES-13 satellite, which provides regular weather images every 15 minutes, is a valuable tool for meteorologists and climatologists. The geostationary satellite has been providing coverage of the U.S. East Coast since April 14, 2010. Not only can it produce satellite images both in the visible and infrared channels, but it can also take in and relay back a lot of meteorological information that actually is used in our various weather models, such as the Global Forecast System (GFS) and the European Centre for Medium-Range Weather Forecasts (ECMWF). These are valuable tools that NASA/NOAA use to monitor our entire weather and climate across the globe. GOES-14 – the

What is GPS meterology? Global Positioning System (GPS) Meteorology is the application of GPS data to the monitoring and analyses of atmospheric conditions. Atmospheric monitoring can be done by both ground-based and space-based GPS applications. GPS satellites transmit radio signals that can be inverted to measure atmospheric profiles of refractivity. The refractivity profile can be transformed to profiles of tropospheric humidity given a temperature profile. Ground-based GPS receivers at fixed locations can be used to gather data that can be used to determine integrated Precipitable Water Vapor (PWV). Atmospheric scientists have shown that GPS-determined PWV observations can significantly improve weather forecasting accuracy. Why is measurement of PWV important?
