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. - 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.
- Suitable WMS are
found that can display mapped climate change data values.
- 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).
- 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.
- 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.
- 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.
- User downloads climate
meteorological time series for selected parameters through the
GeoBrowser and standard web services and formats for use in subsequent
processing.
