Zoom map in/out
There are two ways to zoom the map to different regions; a click-and-drag zoom window 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., 4S-40N, 20W-95E).

• Click-and-drag zoom window
  
  1. Click and drag a window on the map over the region of interest. The map will automatically zoom to that region when the mouse button is released.

2. Click on the map at the point of interest. The analysis will be based on the average of the data within the grid box of the size indicated in Step 1 closest 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.

  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 to the left of the graph.

• 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).
