Microscale Siting Considerations

According to The World Meteorological Organization Commission for Instruments and Methods of Observation, “Wind is the greatest source of disturbance in precipitation measurement.” As early as 1769, William Heberden wrote about the variation of precipitation with...

Mesoscale Siting Considerations

Cities Influence Distribution of Precipitation At the mesoscale, cities can influence the distribution of precipitation. This phenomenon is well documented in the five-year study of precipitation called METROMEX (Metropolitan Meteorological Experiment), which...

Siting Precipitation Gauges to Minimize Measurement Errors

We are often asking a precipitation gauge that is measuring a 0.2 to 0.32 square meter sample to represent the precipitation of a 1000 square meter or larger geographic area. The spatial distribution of precipitation is spatially non-uniform and often random at the...
