On Monday, 11 July from 3:00 p.m. through Wednesday, 13 July until 5:00 p.m. (USA Mountain Time), NSIDC data distribution, services, and Web site will be unavailable to accommodate a major upgrade to our data center.

Use the menus to choose the hemisphere, date, and type of image to view. Your changes should take effect immediately.
To download the image use your browser's Save function (usually a right-click menu option).
It is possible to select an image that doesn't exist - either the date is out of range or the data are missing for some other reason. This results in a NO DATA image or a regular image with the caption "Insufficient Data Available".
The viewer will always return the most recent Conc Trends map or Extent Anomalies plot regardless of the year selected.
The buttons above the image control the animation.
|Display previous image|

|Auto step (play) in reverse|
|Auto step (play) forward|
|Rewind to the beginning of the time series|
|Advance to the end of the time series|
Checking Fixed Month Animations causes the auto step to increment the year only. Otherwise, the month is incremented and then the year.
Checking Auto Rewind at End causes the animation to loop. Otherwise, the animation stops when it hits the end of the time series.
The Slower and Faster buttons control the rate of the auto stepping. Each button press slows down or steps up the animation speed.
