Title: isohyetal_cnty
Contributors:- Polygon data
- 1997
Summary: COVERAGE DESCRIPTION: The 'PRECIPITATION' layer represents lines of equal rainfall (isohyets) based on long-term mean annual precipitation data compiled from USGS, California Department of Water Resources,and California Division of Mines map and information sources. Source maps are based primarily on U.S. Weather Service data for approximately 800 precipitation stations. In the Los Angeles and San Francisco Bay areas the USWS data has been supplemented by county and local agency precipitation data. The data was collected over a sixty year period (1900-1960). Minimum mapping unit is 1000+ acres. The isohyetal contour intervals are variable due to the degree of variation of annual precipitation with horizontal distance.

Title: Hydrogen Sulfide: California State Area Designations, 2008-2011
Contributors:- Polygon data

- Stephen P. Teale Data Center (Calif.).
- California. Air Resources Board. Planning and Technical Support Division
Summary: This polygon shapefile contains area designations of hydrogen sulfide levels in California as required under Health and Safety Code section 39608. The designations are consistent with the criteria established in the California Code of Regulations, title 17, sections 70300 through 70306, and Appendices 1 through 3, thereof. There are four possible designation categories: attainment, nonattainment, nonattainment-transitional, and unclassified. Nonattainment areas are geographic areas which have not met National Ambient Air Quality Standards for hydrogen sulfide air pollution. The State area designations are reviewed annually and approved by the State Air Resources Board. Projection: Teale Albers, NAD83 This shapefile can be used to identify hydrogen sulfide pollution area designations from the prior three-year period (2008-2011) in accordance with the California State Ambient Air Quality Standard.

- California. Air Resources Board. Planning and Technical Support Division
Summary: This polygon shapefile shows area designations in California as required under Health and Safety Code section 39608 for ozone, nitrogen dioxide, sulfur dioxide, lead, and visibility reducing particles. Visibility-reducing particles consist of suspended particulate matter, which is a complex mixture of tiny particles that consists of dry solid fragments, solid cores with liquid coatings, and small droplets of liquid. These particles vary greatly in shape, size and chemical composition, and can be made up of many different materials such as metals, soot, soil, dust, and salt. The designations are consistent with the criteria established in the California Code of Regulations, title 17, sections 70300 through 70306, and Appendices 1 through 3, thereof. There are three possible designation categories for lead (attainment, nonattainment, and unclassified), and there are four possible designation categories for ozone, nitrogen dioxide, sulfur dioxide, and visibility reducing particles (attainment, nonattainment, nonattainment-transitional, and unclassified). In addition, ozone nonattainment areas have been assigned a classification, commensurate with the severity of their air quality problem, under Health and Safety Code section 40921.5. The State area designations are reviewed annually and approved by the State Air Resources Board. Projection: Teale Albers, NAD83 This shapefile can be used to identify visibility reducing particle area designations from the prior three-year period (2008-2011) in accordance with the California State Ambient Air Quality Standard.

The State area designations are reviewed annually and approved by the State Air Resources Board. In February 2011, the staff proposed a number of changes for ozone. The Board approved the proposed changes at a public hearing in May 2011. The Office of Administrative Law (OAL) approved and filed the 2011 State Area Designations rulemaking on September 8, 2011. The regulations became effective on October 8, 2011. Updated: 11/28/11 This layer is presented in the WGS84 coordinate system for web display purposes.
