Subject: | SGP/GPS/X1 - GPS antenna upgrades |
DataStreams: | sgp30wpdngpsX1.c1 |
Description: | Seth Gutman from NOAA/FSL informed me that the GPS antennas at three of the sites in their network were replaced with newer models. These newer antennas should result in better retrievals of PWV from the GPS. These sites and the dates the antennas where changed are: Lamont 12/23/1999 Purcell 12/26/1999 Plattville 12/16/1999 |

Subject: | SGP/WPDN/X1 - Reprocessed: WPDN GPS errors in station info |
DataStreams: | sgp30wpdngpsX1.c1 |
Description: | Starting 10/18/05, there were problems with the station information in the sgp30wpdngpsX1.c1 data. There were extra stations listed with shortened station abbreviations and shortened long names. The data itself was okay, there were just extra stations listed. The data for 10/18/05 - 08/27/06 were reprocessed and archived in October, 2006. |
