Climate Prediction Center (CPC) Global Precipitation Time Series

Dataset Identification:

Resource Abstract:
The global precipitation time series provides time series charts showing observations of daily precipitation as well as accumulated precipitation compared to normal accumulated amounts for various stations around the world. These charts are created for different scales of time (30, 90, 365 days). Each station has a graphic that contains two charts. The first chart in the graphic is a time series in the format of a line graph, representing accumulated precipitation for each day in the time series compared to the accumulated normal amount of precipitation. The second chart is a bar graph displaying actual daily precipitation. The total accumulation and surplus or deficit amounts are displayed as text on the charts representing the entire time scale, in both inches and millimeters. The graphics are updated daily and the graphics reflect the updated observations and accumulated precipitation amounts including the latest daily data available. The available graphics are rotated, meaning that only the most recently created graphics are available. Previously made graphics are not archived.

purpose:
The global precipitation time series was created to provide a graphical representation of observed precipitation amounts as well as information about the daily accumulated precipitation in comparison to normal accumulation amounts for stations across the globe. This provides information about the estimated deficit and surplus of accumulated precipitation in comparison to normal accumulated amounts.

Additional information on resource:
Archives of these graphics are unavailable. The website only makes the latest updated graphics available. Example graphic in browse graphics file description section below contains two charts representing station-based observed precipitation in Washington D.C. for the latest 30-day period. The top chart is a time series of accumulated precipitation from the beginning to the end of the time period in the displayed time series. The values are displayed compared to the normal accumulated amount, which is the thin diagonal line in the chart. A green shaded area under a curve represents surplus precipitation values, whereas brown shaded areas represents deficit precipitation values. The bottom chart shows a bar graph of daily observed values in the same time period as the top chart. The period total and deficit is printed on the bottom chart. Both charts show the values on the left of the charts in inches and the right side of the chart in millimeters.

Resource lineage description
Processing Step
description Calculated daily accumulated precipitation (based on station observations) and estimated normal accumulated precipitation amounts are used to create the line plot chart in the graphic. Station observations of daily precipitation are used to display values in the bar graph chart in the graphic. Normal accumulated precipitation values are derived values and come from a dataset maintained by George Fulwood at CPC.

NonQuantitativeAttributeAccuracy
measure Description  Quality of the analysis relies heavily on the input observational datasets used. There is quality controlling of these input datasets but the specifics of how each are checked must be inspected separately. Internal CPC members that have access to the data can evaluate the quality by accessing the GrADs control files and data. This data is not available to the public.
