Google Earth Applications in California – Improving dissemination of climate adaptation information

This page provides access to applications in Google Earth and google maps that have been developed for the project working on climate change science, impacts and adaptation in California.
Multiple Authors

Welcome to the California part of the SEI Google Earth project on the use and representation of climate information. The second case study for this project is in Kenya.

This page provides access to several applications in Google Earth and google maps that have been developed for the project by scientists working on climate change science, impacts and adaptation in California. Data and information are presented in various ways, including thematic overlays, animations, scientific reports and interactive charts and tables. These layers cover topics ranging from downscaled climate projections, fire threat, landcover and habitat, population projections, and sea level rise in the bay area.

Viewing Animations

* Each of the applications below represents an animation that can be viewed on Google Earth.

* To view the animation, Google Earth needs to be installed and running.

* Click on the link and either Open With > Google Earth; or Save the file on your desktop, and open it in Google Earth.

IMPORTANT TIP: Run only one animation at a time – these animations can be processor intensive!

California Climate Data Guidance

Climate Data on a grid (and more)

This multi-scale, interactive application facilitates access to climate projections (precipitation and temperature) data, fire threat and landcover information, and urban population projections. Only data appropriate for the current scale of the GE viewport is made available to the user; 3 scales of interaction are provided. VIEW LAYER

COARSE SCALE (Tip! current scale=3 on top-left of viewport) The coarse-resolution grid (in blue), is of 0.5 degree latitude-longitude resolution. At this resolution only the climate data is provided, the other datasets being at too fine a resolution to aggregate meaningfully upto this scale. Further guidance for this layer can be found on this page.

Snow Depth

Screenshot showing snow depth

An animation of modeled weekly average snow accumulation in the south forkAmerican River watershed, from a 1971-1999 reference period. The animation is based on hydrologic modeling of the EID water system using the Water Evaluation and Planning System. Cooler colors correspond to deeper weekly snow depths.

Tips: From the Places panel, click on “Overview” to read about the application.

Snow Loss under Climate Change

Screenshot showing snow loss

An animation of modeled losses in weekly average snow accumulation in the south fork American River watershed, for a future 2010-2049 period as compared to the 1971-1999 reference period. The animation is based on hydrologic modeling of the EID water system using the Water Evaluation and Planning System. Warmer (redder) colors correspond to greater snow losses. Values are in percent losses.

VIEW LAYER

About

This is a selection of 6 animations of average annual temperature projections into the future. The overlays presented are under 3 climate projections and two emissions scenarios, from 2010 to 2100, and are presented as differences from a historical average annual temperature calculated for a reference period of 1961-1990. This application loads all six animations into one Google Earth layer – each animation can be viewed one at a time using radio folders.

Data Sources

ENGR

Santa Clara University

Tips

  • If you pause the animation and click on any cell, the corresponding temperature difference for that year and selected cell is displayed (in degrees Celsius).
  • It may take close to 30 seconds to load this layer.

Notes

The original data were on a 1/8 degree grid. To reduce the file size, the Google Earth animations provided upon clicking “View Layer” are produced from data aggregated to 0.5 degree grids.

The same animations were also produced at original data resolution of 1/8 degree latitude-longitude. These can be accessed for the six projections individually here: NOTE that these files, approximately 6 Mb in size, will take up to a minute to load, and may not render perfectly on Google Earth, due to the very large number of polygons loaded for every time step of the animation.

El Dorado Irrigation District (EID) – Using WEAP

El Dorado WEAP work on the Adaptation Layer

SEI has established collaboration with the El Dorado Irrigation District, a water purveyor on the western slope of the Sierra Nevada Mountains, to investigate the potential impacts of climate change on a water system that depends to a large degree on the accumulation of snow at high elevation during the winter and the progressive melting of this snow during the late spring and early summer. A WEAP application of the system has been developed in order to test drought management triggers and actions that were defined by the district assuming that historic hydrologic patterns will be representative of future conditions. Climate change calls this assumption into question. This project will introduce notions of uncertainty and risk management into the definition of drought plan triggers and actions adopted by the district, as well as other long-term actions being contemplated by the district.

This is a selection of 12 overlays of modeled Burnt Area into the future. The overlays presented are under 3 climate projections and 2 emissions scenarios, for two 30-year time periods centered on 2050 and 2085, relative to a 30-year reference period centered on 1975. Values 0.0 to 4.0 represent the ratio of future burned area to the reference period – warmer colors represent higher burned area relative to the reference period. For example, a value of 4.0 corresponds to modeled future burned area at least four times as large as during the reference period.
