Help on the Results MapX
This window can be dragged by its header, and can be resized from the bottom right corner.
Clicking the Layers button - the blue square in the top left of the Results Map - will display a list of map layers you can add or remove
from the currently displayed map view.
The Results Map and the Results Table
- The Results Map displays the centroids of the geographic bounds of all the results returned by the search.
- Results that are displayed in the current map view will be highlighted in blue and brought to the top of the Results Table.
- As the map is panned or zoomed, the highlighted rows in the table will update.
- If you click on a centroid on the map, it will turn yellow and display a popup with details for that project/dataset - including a link to the landing page. The bounds for the project(s)/dataset(s) selected will be displayed in red. The selected result(s) will be highlighted in red and brought to the top of the table.
- The default table sorting order is: Selected, Visible, Date (descending), but this can be changed by clicking on column headers in the table.
- Selecting Show on Map for an individual row will both display the geographic bounds for that result on a mini map, and also display the bounds and highlight the centroid on the Results Map.
- Clicking the 'Show boundaries' checkbox at the top of the Results Map will display all the bounds for the filtered results.
Defining a search area on the Results Map
- If you click on the Rectangle or Polygon icons in the top right of the Results Map, you can define a search area which will be added to any other search criteria already selected.
- After you have drawn a polygon, you can edit it using the Edit Geometry dropdown in the search form at the top.
- Clicking Clear in the map will clear any drawn polygon.
- Clicking Search in the map, or Search on the form will have the same effect.
- The returned results will be any projects/datasets with bounds that intersect the polygon.
- Use the Exclude project/datasets checkbox to exclude any projects/datasets that cover the whole Antarctic region.

Polar MM5 model output over Antarctica and high-latitude Southern Ocean during 1993

None | 1993-01-01 | Bromwich, David | No project link provided | This gridded dataset consists of output from the Polar MM5, a version of the Pennsylvania State University / National Center for Atmospheric Research Fifth Generation Mesoscale Model (MM5; version 2) modified for use over extensive ice sheets. More information on the Polar MM5, including a model description and validation studies, is available at http://www-bprc.mps.ohio-state.edu. A series of 72-h non-hydrostatic forecasts are run for a 1-y period (Jan 1993-Dec 1993) overAntarctica and the high-latitude Southern Ocean. The first 24-h of each forecast are discarded for spin up. The horizontal grid resolution is 60-km, with 120 grid points in the x and y direction. The model topography data are interpolated from a 5-km resolution digital elevation model. The ice shelves are manually identified from climatic maps, and represented as permanent ice. The vertical resolution is represented by 28 sigma levels, with the lowest at 11-m above ground level. The initial and boundary conditions include 12-hourly ECMWF TOGA (2.5 deg) global analysis for the surface and upper air variables, 6-hourly ECMWF TOGA (1.125 deg) global analysis for sea surface temperature, and daily DMSP SSM/I polar gridded sea ice concentration (25-km) from the National Snow and Ice Data Center. Model output is in native MM5 format, and available variables are numerous, The reader is referred to the MM5 website for a complete list of variables, as well as detailed documentation and tools for reading and plotting the data.
