Which of the following characteristics of radar-derived precipitation don't
apply to rain gauge measurements? - ANSWER x It has good space and
time resolution.
x It is remotely sensed data.
Because rain gauges are surface-based, direct measurements, they
provide _____. - ANSWER estimates with different types of errors than
radars

x particle shapes
Satellite rainfall estimates are generally higher resolution than radar
estimates. - ANSWER True

every 1 m/s. - ANSWER 1 | 2.2
A Z-R relationship provides good _____ if it correctly represents the
_____. - ANSWER rainfall rate estimates | drop size distribution
The best rain gauge measurement will occur with _____. - ANSWER x

_____. - ANSWER gauge locations
Components of the hydrologic cycle include precipitation, condensation,
surface runoff, and ________ - ANSWER evaporation

Earth. - ANSWER less than 1%
Springs are fed from _______ - ANSWER groundwater
In addition to weather conditions, which of the following has a direct
influence on plant transpiration? - ANSWER Plant type, plant canopy
density, plant coverage
______-type soils have larger pore spaces and allow for greater
infiltration and percolation than _____ -type soils, which have more pore
space and can hold more water. - ANSWER sandy, clay
The Multisensor Precipitation Estimator provides analysis of gridded
precipitation accumulation using information from which of the following?
- ANSWER x Radar
x Rain gauges

Which of the following MPE functions is very important for assuring
appropriate adjustments to radar QPE fields? - ANSWER Evaluating and
editing gauge reports
Why might the Multisensor Mosaic be the best option in areas of radar
blockage? - ANSWER It uses gauge-based QPE in areas of poor radar
coverage.
