The data will continue to be updated every year. Precipitation data is provided for each month of the most recent water year, total precipitation for the water year, the percent of normal for the water year to date, and the percent of the entire water year we have received to date. Data availability over most of the Canadian Arctic is restricted to the mid-1940s to present. Observations at co-located sites were sometimes joined in order to create longer time series. These daily summaries provide a cumulative precipitation estimate from 1200GMT yesterday to 1200 GMT (daily) or 1200 GMT 7 days ago to 1200 GMT today (weekly). 24-hours ending at midnight for selected automatic-reporting rain gages (Provisional data, subject to change) Report generated: J10:08. precip-itation total, inches undefined: 09429600: colorado river below laguna dam, az-ca : 08/19 03:30 mst : 0.00 : 333709116405101: thomas mtn precip gage nr anza ca : 08/19 03:00 pdt : 0.00 : 340526116561301: mill c precip nr forest falls ca : 08/19 02:45 pdt : 0.
#CA PRECIPITATION TOTALS UPDATE#
The time periods of the data vary by location, with the oldest data available from the early 1880s at some stations to the most recent update in 2017. More Information: Air Temperature Bias Correction Metadata and Resources. Southwest California CNRFC Southwest California CNRFC California. The Snow Survey and Water Supply Forecasting Program is actively working on a correction technique for this issue. Rainfall amounts ranging from 1 to 1.5 inches may be possible along the south-central coastline of California from late Sunday to Monday, said Smithmyer. Observations - Rainfall and River Levels. Adjusted precipitation data incorporate adjustments (derived from comparison of instruments) to the original station data to account for discontinuities from non-climatic factors, such as instrument changes or station relocation. It has been determined that use of the linear least-squares regression algorithm has resulted in a data bias. The IEM attempts to take the METAR reports of precipitation and then provide just the hourly precipitation totals. Adjusted Precipitation (AHCCD) The Adjusted Precipitation data consist of monthly, seasonal and annual totals of daily adjusted rain, snow and total precipitation (millimetres) for 464 locations in Canada.
