Daily global land surface temperature at 1km (Copernicus)

MODIS Aqua Land Surface Temperature Emissivity Daily L3 Global 1km
land ESA ESA Copernicus active
In plain English

What it measures. Measures how hot or cold the actual ground surface is, day and night, at 1-kilometre detail, along with how readily different surfaces emit heat.

How it's made. Derived from clear-sky MODIS observations on NASA's Aqua satellite and produced as daily global tiles on a 1-kilometre grid.

How & where you'd use it. Valuable for studying heatwaves, urban heat islands, drought, and crop conditions, and as a daily climate-monitoring input.

Official description

The MODIS Aqua MYD11A1 Version 6.1 product provides daily per-pixel Land Surface Temperature and Emissivity (LST&E) at 1 km spatial resolution. The data are generated from the MYD11_L2 swath product and distributed on a 1,200 × 1,200 km grid. Pixel temperature values are derived from clear-sky observations; at latitudes above 30°, where multiple clear-sky observations may occur within a day, the pixel value represents the average of all qualifying measurements. The product includes both daytime and nighttime surface temperature bands, along with quality control layers, observation times, view zenith angles, clear-sky coverage information, and emissivity estimates for MODIS Bands 31 and 32 derived from land cover types.
