Precipitation

Precipitation amounts and their spatial and seasonal variations are basic to all hydrologic and natural resource studies. The original RCEW gauge network, established in 1960-1961, consisted of 83 unshielded 12“ (30.48 cm) weighing-recording gauges. Because most of the precipitation that falls on the higher elevations of RCEW is snow, there was a significant undercatch by the network of single, unshielded gauges. Undercatch of precipitation, especially of snow by gauges that are not protected naturally, is a major problem in obtaining accurate point measurements. Undercatch of snow is especially acute in windy environments such as those encountered on areas within the RCEW. Therefore, during 1967-1968, the network was converted to 46 dual-gauge installations which were designed to more accurately measure snowfall. The dual-gauge system consists of an unshielded and a shielded universal-recording gauge with orifices 3.05 m above ground. The shield is an Alter-type with the shield’s baffles individually constrained at an angle of 30° from vertical. The gauge network was further reduced in the mid-1990's and we now have 26 precipitation measurement sites. A very detailed report of the precipitation gauge network was published in 2001.

This graph reflects the raw data that has been collected and may sometimes go wildly off-scale. Real data does that sometimes. To zoom in the time scale hold the left mouse button down and drag across the region of interest. To select a smaller y-data range hold the left mouse button down inside the graphed data area and drag to the scale of interest. To pan through time hold the shift key down and the drag the mouse left or right while holding the left button down. Double click to return to full time scale. It's not as hard to do as it sounds but it may take some practice.

The precipitation record is updated annually and is normally processed and completed in January for the following year. Click icon in “Site” column to download zipped data file.
