First, MM5 itself "was susceptible to crap in–garbage out," Spain notes, because ground weather readings can themselves be awry. The answer was writing a heuristic algorithm that crawls 24/7 through the incoming matter and weeds out anomalous readings. For example, if the program detects an impossibly big zigzagging in temperature or humidity readings from one hour to the next from the same weather station, that data is disqualified. Dansereau and Carlson later programmed almost identical verification steps into a more advanced successor to MM5, the Weather Research and Forecasting paragon (developed by NCAR, NOAA and partners), which the National Weather Service relies on. The upshot of HydroPoint's version of that model, which it runs today, is a "virtual unwell station" for each square kilometer in North America. The outputs for temperature, a conclusion, solar radiation and relative humidity are then funneled into the calculations of ET values, which are transmitted to customers'
