Thanks to the efforts of Seth Gutman <Gutman at zeus.fsl.noaa.gov> a new
met package has been installed at USNO.  The data should begin to be
reported shortly.  The package is a GPS Surface Observing System (see
http://maia.usno.navy.mil/eo/gsos-met.pdf) from NOAA's Forecast Systems
Laboratory with the following specifications:

       Manufacturer           : Vaisala
       Data Frequency         : 15 seconds
       Accuracy (% rel h)     : +/-1%(0...90%RH)
                              : +/-2%(90...100%RH)
       Effective Dates        : 21-AUG-2001 - present
       Notes                  : NOAA GSOS # 062

       Effective Dates        : 21-AUG-2001 - present
       Notes                  : NOAA GSOS # 062

8.3  Temperature Sensor Model : PT100 RTD 1/s DIN 43760B
       Manufacturer           : Vaisala

In addition to Seth, I would like to thank Ernie Marion and his
colleagues at NOAA/NGS's GODC for their help with the installation.
