(Left): Near-real-time PWV estimates for stations located in North American. (Right): Same as the map on the left but showing only the contiguous United States. These products have a typical latency of 18~60 minutes. The delay in the availability of the public RINEX data is the primary driver of the latency. We are currently processing 1,362 stations.  Any data that arrives within a specified period is processed and included in the current epoch. 

The near-real-time RTNet PWV service can process GNSS stations (using RINEX or real-time data) from any global location. We use high-quality multi-GNSS satellite orbit and clock products.  The PWV and slant delay products are then made available to our end-users.
