NASA | GPM Wraps Up Cold Season Field Campaign

The video discusses a successful field campaign in Ontario, Canada, aimed at collecting data on snowfall intensities to improve detection from space using the GPM core satellite. Despite less snowfall than expected, the team completed 14 missions over six weeks, gathering essential data. The process involved extensive quality control of data from ground instruments, aircraft, and satellite simulators. The ultimate goal is to develop algorithms for accurate snowfall retrieval from space.

What was one of the main objectives of the experiment conducted in Ontario, Canada?

• To measure the temperature variations in the region

• To test the range of snowfall intensities for satellite detection

• To study the impact of snow on local wildlife

• To develop new snow removal techniques

How many missions were flown during the six-week field campaign?

• 10 missions

• 16 missions

• 12 missions

• 14 missions

What was a challenge faced during the field campaign regarding snowfall events?

• The snowfall events were less frequent and lighter than expected

• The snowfall events were too frequent

• The snowfall events were too short in duration

• The snowfall events were heavier than expected

What is the purpose of quality controlling the data collected during the experiment?

• To ensure the data is free from errors and usable

• To enhance the visual quality of the data

• To reduce the size of the data sets

• To prepare the data for public release

What is the ultimate goal of connecting field campaign measurements to space observations?

• To improve weather forecasting models

• To develop an algorithm for retrieving snowfall data from space

• To create a global snowfall database

• To enhance satellite communication systems
