1. Change the date in the text box above the map using the same format as the date already shown (e.g., 1-16 Jan 2006). If you enter a single date (e.g., 5 Jan 2006), then the interface will select the nearest 16-day period for which data is available.
2. Click the "Redraw" button.

Animate data from multiple 16-day periods
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., "1-16 Jan 2005 to 17 Jan 2006 - 1 Feb 2006" or "8 Jan 2006 to 25 Jan 2006").
2. Click the "Redraw" button.

Overlay adminstrative boundaries
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 overlays 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 click-and-drag option and the latitude/longitude text boxes. Note that the map can not display areas outside of the region first shown on the interface (i.e., 0° - 40°N, 20°W - 20°E).

• Click-and-drag


1. Click the left mouse button at the upper-left corner of the region to which you would like to zoom.
2. While holding down the button, drag the mouse to the lower-right corner of the region to which you would like to zoom.
3. Release the left mouse button. The map will redraw automatically.

• 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 data to be spatially averaged.
2. 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 the grid box nearest to this point.

• 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.
  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.
