TOMS Online Visualization and Analysis

Daily Level 3 Global Gridded Products

Home

This interface is designed for visualization and analysis of the version 8 TOMS daily level 3 global 1.0°x1.25° gridded products from the Earth Probe (EP), Meteor-3 and Nimbus-7. Users can generate plots or ASCII output for Lat-Lon Map, Time series, and Hovmoller diagram. Animation is available for Lat-Lon Map.

EP TOMS data after 2001 should NOT be used for trend analysis (read more). Production of EP TOMS real-time data ended Dec 31, 2005, please use OMI data now instead.

Select Visualization:

Lat-Lon map, Time-averaged Preferences

Get the most recent preferences based on the service and parameter selections.

Set the width of the plot image (in pixels)

Set the height of the plot image (in pixels)

Decoration Flag

Determine whether decorations (axes reticles, labels, etc.) are displayed for the resultant images

Mode:	Dynamic Pre-Defined Custom
Palette:
Min Value:	Overrides ALL parameter min/max values.
Max Value:	Overrides ALL parameter min/max values.

Select color map mode, select a palette, or, if shown in this preference bloc, specify min and max parameter value to map. The 'Palette' and Min/Max Value options are enabled only when the 'Custom' mode is selected. Values entered for 'Min Value' and 'Max Value' will override parameter specific values for parameter min and max, respectively.

Select a projection for the plot(s)

Determine whether the pixel interpolation should use a smoothing routine
