Tools for Analyzing Weather and Climate Data in California
Temperature and Precipitation:
US Divisional Climate Data: Uses NOAA Divisional data (1895-present, monthly) to generate time series graphs of temperature and precipitation for climate divisions and states for California and the US.
California Climate Tracker: Uses PRISM data (1895-present, monthly) to generate time series graphs of temperature and precipitation for 12 regions in California.
Westmap: Uses PRISM data (1895-present, monthly) to create time series graphs and maps of temperature and precipitation for states, counties, climate divisons, hydrologic units, and user-specified polygons or pixels in the western US.
North American Freezing Level Tracker: Uses NCEP/NCAR Global Reanalysis data (1948-present) to create time series graphs of freezing level at a user-specified location in North America.
WestWide Drought Tracker: Uses PRISM data (1895-present) to calculate Palmer Index, SPI, SPEI, temperature, and precipitation and produces maps by county for the western US. Time series graphs can be generated by pixel, state, county, hydro unit, climate division, or Predictive Services areas.
