| Function | Description |
|---|
| Lat-Lon Map, Time-averaged: | This function provides a time-averaged color data plot for a specified area. The values plotted are the mean (time average) value of the data product calculated for the specified time interval. (Note that these averages are calculated from the monthly average data values in the SMI products, not from the original daily data product values.)
|
| Time Series, Area-averaged: | This function provides an X-Y data plot. The monthly value of the data product, averaged over the entire specified area of interest, is plotted as a function of time for any specified time interval. A time series for a single point is also supported.
|
| Animation, Lat-Lon Maps: | This function provides an area plot animation of the requested data product, in monthly increments, for any specified time interval.
|
| Time-Lon Hovmoller, Lat-averaged: | This function provides a Hovmoller time vs. longitude color plot. For a specified area, the average monthly value of the data product is displayed with longitude as the X-axis and time as the Y-axis.
|
| Time-Lat Hovmoller, Lon-averaged: | This function provides a Hovmoller time vs. latitude color plot. For a specified area, the average monthly value of the data product is displayed with latitude as the X-axis and time as the Y-axis.
|
| Option | Description |
|---|
| Pre-defined: | Uses the color palette with the pre-specified default range of assigned values. This may be a linear or logarithmic scale palette. |
| Dynamic: | Uses the minimum and maximum values of the data product in the specified area to create a linear scale color palette. |
| Customized: | Allows user specification of minimum and maximum values for the color palette. A linear scale color palette will be created based on these minimum and maximum values. |
| Option | Description |
|---|
| Dynamic: | Dynamically sets the minimum, maximum, and interval values for the Time Series Plot Y-axis. |
| Customized: | Allows user to specify the minimum, maximum, and interval values for the Time Series Plot Y-axis. |

| This pull-down menu provides 11 resolution options for Area/Hovmoller ASCII outputs. Please note that the original data is in Equidistant Cylindrical Map Projection with Latitude/Longitude steps of 0.0878906 degrees. Currently, the output resolutions available are 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, and 5.0 degrees. For a given resolution selection, the program steps through each of the possible lat/lon, lon/time or lat/time points, and sets their values to be the same of the nearest point at the original resolution. No interpolation or averaging is performed. If you have suggestions for adding new resolutions, please contact us at help@daac.gsfc.nasa.gov.
