35 Appendix G. Descriptions of weather/climate monitoring networks

  • Network weaknesses:

o Density of station coverage is low.

o Shorter periods of record for western United States.

The CASTNet network is primarily is an air-quality-monitoring network managed by the EPA. The elements shown here are intended to support interpretation of measured air-quality parameters such as ozone, nitrates, sulfides, etc., which also are measured at CASTNet sites.

G.5. California Irrigation Management Information System (CIMIS) Network

  • Purpose of network: provide meteorological data to assist in irrigation activities and other water resource management issues for California agricultural interests.
  • Primary management agencies: California Department of Water Resources.
  • Data website: http://www.cimis.water.ca.gov/cimis/data.jsp.
  • Measured weather/climate elements:

o Air temperature.

o Precipitation.

o Relative humidity.

o Wind speed and direction.

o Solar radiation.

o Soil temperature and moisture (some sites).

  • Sampling frequency: hourly.
  • Reporting frequency: hourly.
  • Estimated station cost: unknown.
  • Network strengths:

o Near-real-time.

o Sites are generally well-maintained.

o Data access.
