  1. Name different types of satellite orbits.
  1. What type of orbit do the following satellites have?
  1. TRMM
  2. Aqua
  1. State at least two strengths of atmospheric model data.

10.What is one limitation of MODIS that results in missing/un-available snow observations?

11.Which of the following parameters are not directly derived from satellites but are derived from models?

  1. Rain Rate
  2. Run off
  3. Snow Fraction

12.Which satellite data requires more processing? Level-1 or Level-3?

13.Which of the following sensors has larger swath size?

  1. PR

14.What is the temporal resolution of TMPA data?

15.Does MODIS provide measurements over Arctic region?

16.List two web-sites where MODIS Standard Product is available.

17.Which parameters are available in MODSCAG?

18.Which hydrology model and TRMM data product is used by SERVIR?

19.Which parameters are monitored by SERVIR over Africa?

20.Go to and list the parameters shown in the three maps that appear on the main page.

  1. Evapotranspiration
  2. Soil Moisture
  3. Soil Type
  4. Snowmelt

23.Do you agree with the following statements?

  1. There is no need of surface-based observations since there are remote sensing and model-based data available globally (Agree Disagree)
  2. Remote sensing measurements are more accurate than surface-based observations (Agree Disagree)

24.From the following streamflow map which river shows highest flood potential? Either name the river or mark on the map.

25.In the following run-off (left) and snowmelt (right) maps from GLDAS for April 2013, identify wherelarge run-off (color light blue to yellow) is NOT associated with snowmelt (you can draw on the map or state the broad geographical region).
