Here is an example of precipitable water (PW) from the SPC Mesoanalysis and observed from the GOES-R LAP Algorithm:While there are slight discrepancies between the two data sets (and obvious noise in the GOES-R data), they are actually fairly similar with respect to trends and location of the highest PW values. The gradients of PW match very closely. This tool will be very useful to track increasing precipitable water.
