unit 2, exam 1 Flashcards
ECVs
Essential Climate Variables
measurable values to help study process and predict
over 50 variables
2 categories of ECVs
in-situ
remote sensing
in-situ
measurable with direct contact
considered more accurate
remote sensing
obtained at a distance
ex)polar and geostationary
Geostationary satelites
satelite remains exact over a location-higher orbit
Pro: see all points at same time
Con: low resolution due to distance from earth
Polar
lower orbit-fixed plane while earth rotates on axis
Pro:high resolution, see higher lat better
Con: large gaps in spatial and temporal coverage
Co-operative weather observer program COOP
us citizen data to construct weather
Automated surface observing system ASOS
an automated electric system that replaces the need for some of the COOP manual observations.
US historical climatetology network USHCN
best of the best COOP sites
historical stability
