What is the land surface temperature?
The Land Surface Temperature (LST) is the radiative skin temperature of the land surface, as measured in the direction of the remote sensor. In turn, the LST influences the partition of energy between ground and vegetation, and determines the surface air temperature.
What is the average day temperature on Earth?
According to GISS, the global mean surface air temperature for that period was estimated to be 57 F (14 C). That would put the planet’s average surface temperature in 2017 at 58.62 F (14.9 C).
Which warms up faster land or water?
It takes less energy to change the temperature of land compared to water. This means that land heats and cools more quickly than water and this difference affects the climate of different areas on Earth.
What are the instruments on the Sentinel 3?
Sentinel-3 is a multi-instrument platform that focuses on ocean surface topography as well as land and sea surface temperature. The platform carries the Sea and Land Surface Temperature Radiometer (SLSTR), the Ocean and Land Colour Instrument (OLCI), as well as a Synthetic Aperature Radar (SAR) and a Microwave Radiometer (MWR).
When does the Copernicus Sentinel 3B come out?
The other two, Sentinel-3B and -3C, are scheduled to launch within the 2017 – 2020 timeframe. Sentinel-3 is a multi-instrument platform that focuses on ocean surface topography as well as land and sea surface temperature.
How is land surface temperature determined in SLSTR?
Land Surface Temperature (LST) is the radiative skin temperature of the land derived from infrared radiation. In the SLSTR project, “skin” temperature refers to the temperature of the top surface when in bare soil conditions, and to the effective emitting temperature of vegetation “canopies” as determined from a view of the top of a canopy.
What is the surface temperature of the land?
Land Surface Temperature Land Surface Temperature (LST) is the radiative skin temperature of the land derived from infrared radiation.
