Spatial coverage in UHI atlas: Central Europe
Short description of Digital elevation data SRTM
The SRTM (Shuttle radar topography mission; Jarvis et al. 2008) digital elevation
data, produced by NASA originally, has a resolution of 90 m at the equator and is
available for over 80 % of the globe.

2.9 Raster Data with Low Resolution (≥0.5 km)
2.9.1 MODIS NDVI Images
Format: raster data (1 km)
Temporal coverage: different examples for spring, summer and autumn (16-day
average)
Spatial coverage in UHI atlas: Central Europe
Short Description of MODIS NDVI Images
Some of MODIS (Moderate resolution imaging spectroradiometer) products provide information on vegetation. One of them is NDVI (Normalized difference vegetation index). Vegetation indices are used for global monitoring of vegetation
conditions and are used in products displaying land cover and land cover changes.
MODIS NDVI data (product codes MYD13A2 and MOD13A2) are provided
every 16 days at 1-km spatial resolution.

2.9.2 MODIS LST Images
Format: raster data (1 km)
Temporal coverage: different examples for spring, summer and autumn (8-day
average)
Spatial coverage in UHI atlas: Central Europe
Short Description of MODIS LST Images
The MODIS global Land Surface Temperature (LST) and Emissivity 8-day data are
composed of the daily 1-km LST product (MOD11A1&MYD11A1) as the average
values of clear-sky LSTs during an 8-day period.
MOD11A2 & MYD11A2 are comprised of daytime and nighttime LSTs, quality
assessment, observation times, view angles, bits of clear sky days and nights, and
emissivities estimated from land cover types.
