Hold the left mouse button down as you drag the Slider control (labelled "Set Fade Level") above the image (or click on the arrow buttons) to fade between 2 Terra MODIS composite images at 18:02 UTC on 22 March 2003 and a corresponding topography image. To zoom, click on the "Zoom" button, and then click the "hand" cursor on the image where you want to center the zoom. To quickly toggle between the first and third images, click in the middle of the grey Slider control area, beneath the word "Fade" in "Set Fade Level".

These images show the extent of snow cover across Colorado. The second RGB composite image (channels 01 and 06) shows cloud as white, with snow cover having a pink/red enhancement.
