Hello! I'm using the API to get precipitation data by sending geographical coordinates (latitude and longitude). I get valid returns but lots of -9999 (missing value). I wonder how does the API work to get the data? Suppose I make a query to retrieve precipitation data for location A, does it look for weather stations near A to get the data? If so, how far would it go to find adjacent weather stations? Thanks in advance!
