Net Radiation

Net radiation is the balance between incoming and outgoing energy at the top of the atmosphere. It is the total energy available to influence climate after light and heat are reflected, absorbed, or emitted by clouds and land.

Land Surface Temperature

Land surface temperatures rise and fall with the heat of the Sun, and they represent how hot or cold the surface would feel to touch. These maps show daytime land temperatures as measured from space.

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.
