These sensors have a relatively higher spatial resolution that is useful for mapping urban land surface temperatures: *

5 points

MODIS and VIIRS

ABI and AVHRR

TIRS and ASTER

Land cover data are required for deriving land surface temperature from remote sensing. *

5 points

True

False

All of the following are causes of Urban Heat Islands, except: *

5 points

Anthropogenic heat

Reduced vegetation in urban areas

Green roofs

Calm and clear weather conditions

Since we have a long time series from multiple satellites/instruments for monitoring Urban Heat Islands, we do not need any in situ measurements. *

5 points

True

False

GOES ABI land surface temperature products are available globally at 10 km resolution. *

5 points

True

False

Which of the following are problems related to Urban Heat Islands? *

5 points

Increased risk of heat-related mortality and morbidity

Increased energy consumption

Degraded water quality

All of the above

These satellites and sensors have daily or twice daily observations: *

5 points

Aqua MODIS

JPSS VIIRS

Landsat 8 OLI

Both a & b

One of the major limitations of remote sensing observations for getting land surface temperatures is:

0 points
