Arctic SDI

Background: Arctic environmental manager/planner is interested in accessing and comparing the forecast outputs of long-term climate models, scenarios, and baselines as those identified by the IPCC but they have no climate modeling expertise. Users have an interest in monitoring forecast changes in temperature and precipitation on a monthly, seasonal, and annual basis for the polar region for facilities management, environmental monitoring, coastal management, and emergency response planning. Outputs include: symbolized model output map services with queryable values in a form and projection that can be readily used in the polar environment; online data services that deliver gridded model output data in selected regions and formats that can be used as input to other decision support models.


Prerequisites:

  • End-user access to software that will present/render gridded map data for climate
  • Authoritative Climate Change model output services are available as WMS and WCS
  • Daily min/max temperature, precipitation, wind direction, and speed for sites of the current climate period accessible as WMS and KML with hyperlinks for graph generation, and via WCS for request and download as NetCDF.
  • Climate change model visualization and data access services are registered with GEOSS CSR


The main steps of the polar ecosystem scenario are as follows.

  1. User works within his application environment (Google Earth, Desktop GIS, GeoBrowser) to query for the availability of Climate Model Scenario data and mapping services registered with GEOSS.
  2. Suitable WMS are found that can display mapped climate change data values.
  3. User configures a request for display of climate data based on a combination of initial conditions/inputs, selected model/type, parameter(s) to be visualized or compared, and the time(s) to be forecast (See http://ipcc-data.org/maps for an interactive example).
  4. User is provided access to visualize the one or more parameters, perhaps even as an animated time series within their client program, in concert with base map data of elevation, orthoimagery, transportation features, facility locations, cities and administrative subdivisions, river networks, vegetation/land cover, population density, environmental monitoring sites, and other sites of interest.
  5. Modeling user is interested climate model output data to feed into other models and decision support systems for water budget calculation, flood and drought planning, coastal erosion, emergency response, and infrastructure planning and management.
  6. User searches for, queries, and evaluates weather data through GeoBrowser and client software, including the generation and display of climate averages (i.e. annual temperature and precipitation graphs) for individual weather stations within the current climate baseline period.
  7. User downloads climate meteorological time series for selected parameters through the GeoBrowser and standard web services and formats for use in subsequent processing.
