Temperature and Precipitation Percentile Maps


One way to depict how a month or season compares to its history is to use a ranking system. NCEI has done this for many years for the climate divisions, states, etc. The maps below depict rankings based on NCEI's 5km gridded dataset, nClimGrid. Each grid point is ranked compared to the historical values in its own period of record.

More information on the methodology behind the rankings can be found here: https://www.ncdc.noaa.gov/monitoring-references/dyk/ranking-definition
