Land Surface Temperature Anomaly
Global Maps Feb 2000 — Apr 2021

Land Surface Temperature Anomaly

These maps depict anomalies in land surface temperatures (LSTs); that is, how much hotter or cooler a region was compared to the long-term average. LST anomalies can indicate heat waves or cold spells.

Carbon Monoxide
Global Maps Mar 2000 — Feb 2017

Carbon Monoxide

When fuels such as coal, wood, and oil burn incompletely, they produce carbon monoxide. The gas is spread by winds and circulation. These maps show monthly averages of CO in the lower atmosphere.

Cloud Fraction
Global Maps Feb 2000 — Apr 2021

Cloud Fraction

In addition to making rain and snow, clouds can have a warming or cooling influence depending on their altitude, type, and when they form. These maps show what fraction of an area was cloudy each month.

Snow Cover
Global Maps Mar 2000 — Apr 2021

Snow Cover

Snow and ice influence climate by reflecting sunlight back into space. When it melts, snow is a source of water for drinking and vegetation; too much snowmelt can lead to floods. These maps show average snow cover by month.
