1. Change the date in the text box above the map using the same format as the date already shown.
2. Click the "Redraw" button.

Animate data from multiple dekads
Any number of time steps may be animated, but the time necessary to load the animation will increase with the number of time steps included in the selection.

1. In the date text box above the map, enter the start and end dates of the time period over which you would like to animate, separated by "to" (e.g., "21-30 Nov 2004 to 21-31 Dec 2004").
2. Click the "Redraw" button.

Overlay adminstrative boundaries and epidemiological mask
Any combination of the available overlay maps may be displayed.

1. Using the "Optional Overlay Maps" table located to the far left of the map, select the maps that you would like to display.
2. Click the "Redraw" button.

Zoom map in/out
There are two ways to zoom the map to different regions; the zoom buttons focus the map on a general area and the latitude/longitude text boxes select specific regions to be displayed. Note that the map can not display areas outside of the region first shown on the interface (i.e., 40S-40N, 20W-50E).

• Zoom buttons
  The zoom buttons are located to the immediate left of the map.


1. Select the appropriate factor by which you want the map to zoom in or out. Note that "x2" zooms the map in and "x1/2" zooms the map out by a factor of 2.
2. Click on the map at the point you would like to have in the center of the zoomed in/out region.

• Specific lat/lon selection
  There are four lat/lon text boxes underneath and to the left of the map.
  
  1. Change the values in the lat/lon text boxes to the limits of the region you would like to display using the text format already shown.
  2. Click the "Redraw" button.

Generate time series analysis

1. Using the "Time Series Region" table to the right of the map, select the size of the region over which you want the precipitation to be spatially averaged.

   The CPC/FEWS RFE2.0 dataset has a very fine resolution (i.e., 0.1°x0.1°). It is therefore prudent to base this type of analysis on an average of multiple grid points.

2. The "Click" table to the immediate left of the map determines whether a click on the map generates a time series or zooms the map in and out. Make sure that the "for Info" option is selected.

3. Click on the map at the point you wish to be analyzed. If you chose a box region in Step 1, then the analysis will be based on the average of the data within that sized box centered on your selected point.

   Note that when selecting a district, it may be useful to zoom in to the region of interest and overlay district boudaries before generating the time series analysis.

• Select specific lat/lon coordinate to analyze
  
  1. Select the size of the region to be included in the analysis from the pull-down menu.
  2. Enter the latitude and longitude of the point of interest, or any point within the district of interest.
  3. Click the "Generate new time series" button.

• Modify graphs
  
  1. Click on any of the graphs to bring up an interactive viewer that will allow you to modify the aesthetics of the selected graph.
  2. Change the values in the text boxes to modify the temporal range of the graph and/or the limits of the vertical axis.
  3. Click the "Redraw" button.

• Download graphs in a variety of formats
  
  1. Click on the graph of interest to bring up the interactive viewer, if you have not already done so (see Modify graphs above).
  2. Select the desired download format (e.g., PostScript, JPEG, GIF, PNG) from the options available in the "Just the Figure Formats" line of the table. Static URLs for the selected image are also available in the Page Fomats line of the table and more information about these page formats can be found by clicking the "Help" button.
