What does TRMM mean?
The Tropical Rainfall Measuring Mission (TRMM) is a joint space mission between NASA and Japan’s National Space Development Agency designed to monitor and study tropical and subtropical precipitation and the associated release of energy.
What does TRMM measure?
The Tropical Rainfall Measuring Mission (TRMM), is the first mission dedicated to measuring tropical and subtropical rainfall through microwave and visible infrared sensors, and includes the first spaceborne rain radar. Tropical rainfall comprises more than two-thirds of global rainfall.
What is TRMM and GPM?
TRMM to GPM to … Tropical Rainfall Measuring Mission (TRMM) was the first step in an evolving process of collecting global precipitation data from space, and helped reveal questions about precipitation measurement that are being addressed by Global Precipitation Measurement (GPM).
How is gpm better than TRMM?
The GMI has a greater frequency range than TRMM’s (13 channels versus 9 channels), which allows GPM to measure precipitation intensity and type through all cloud layers using a wider data swath. One of the most significant evolutions in GPM data is its broader global coverage.
In what range of the electromagnetic spectrum does the TRMM satellite operate in?
Table 4: Characteristics of primary TRMM instruments
| Sensor | Observation Objectives | Frequency/ spectral range |
|---|---|---|
| CERES | Radiation from top of clouds and Earth, energy budget | 0.3 – 5 µm 8.0 – 12.0 µm 0.3 – 100 µm |
| LIS | Lightning distribution | 0.7774 µm |
What are the different types of rainfall?
Types of Rainfall
- Convectional rainfall.
- Orographic or relief rainfall.
- Cyclonic or frontal rainfall.
What is the goal of the TRMM satellite?
TRMM was a research satellite in operation from 1997 to 2015, designed to improve our understanding of the distribution and variability of precipitation within the tropics as part of the water cycle in the current climate system.
What is the goal of the TRMM satellite and its instruments?
The satellite uses several instruments to detect rainfall including radar, microwave imaging, and lightning sensors. Flying at a low orbital altitude of 240 miles (400 kilometers) TRMM’s data collection of tropical precipitation helps improve our understanding about climate and weather.
What replaced TRMM?
Global Precipitation Measurement mission (GPM)
Two Decades of Precipitation Measurement PMM includes two missions – the Tropical Rainfall Measuring Mission (TRMM), which orbited Earth from 1997 to 2015, and its successor, the joint NASA-JAXA Global Precipitation Measurement mission (GPM), which has been collecting data since 2014.
What is GPM in pump?
A pump’s job is not to deliver pressure; rather, it is to deliver a rate of flow, pumping a certain amount of liquid over a given amount of time from a tank or reservoir to the outlet. Flow rates are often referred to in gallons per minute or GPM.
