Normal precipitation is derived from the Parameter-elevation Regressions on Independent Slopes Model (PRISM) climate mapping system developed at Oregon State University. The PRISM gridded climate maps are considered the most detailed, highest-equality spatial climate datasets currently available. The 30-year PRISM normal from 1981-2010 is used for precipitation analysis since 2004. Prior to 2004, the 30-year PRISM normal from 1961-1990 is used. Puerto Rico PRISM data comes from a separate project by the International Institute of Tropical Forestry. PRISM data for Puerto Rico covers the time period 1963-1995. The PRISM data is expressed as a monthly normal rainfall. For durations less than one month, the value for that month is divided by the total days in that month and multiplied by the number of days in the selected field. For example, a 7-day normal for January 10th (ending at 1200 GMT) would be 7/31 of the total normal rainfall for January, while a 14-day normal would be 9/31 of January's normal plus 5/31 of December's normal.
Display and/or analyses requiring spatially distributed precipitation for the following time periods last 7 days, last 14 days, last 30 days, last 60 days, last 90 days, last 180 days, month to date, year to date, and water-year to date (Oct 1) for the climatological periods 1981-2010 (used since 2004), 1961-1990 (used before 2004), or 1963-1995 (Puerto Rico only).
