Abstract:
For the purpose of comparison of Slantpath Water Vapor (SWV) retrieved from a GPS receiver and a microwave radiometer (MR), a campaign design is completed to control the MR to point to a GPS satellite automatically to measure the SWV along the path between GPS satellite and MR. Without changing the hardware of MR, a designed software is set up to operate MR to focus on a GPS satellite using the temporal and positional parameters produced by a GPS receiver. This design is feasible automatically in allweather, which ensures the representativeness and objectivity of the observations, and reduces the expenditure for hiring observers. The preliminary results show that MR can trace well the GPS satellites to retrieve SWV with a satisfactory accuracy by using this campaign design.
