چکیده

Abstruct-The Tropical Rain Measuring Mission (TRMM) precipitation radar (PR) is designed to measure backscatter from rain in order to map the ;mount and extent of rain in the tropical regions. The TRMM F'R also measures the normalized radar cross section (a") of the surface at a nominal resolution of approximately 4.4 km over an incidence range of 018". The Kuband NASA Scatterometer (NSCAT) made 25 km resolution measurements of the surface a ' at incidence angles of 15.5" and higher and at 10.5". A comparison of NSCAT and TRMM PR 0" observations over the Amazon rainforest is presented. The relative calibration and noise levels of the two sensors are compared.

The NASA Scatterometer (NSCAT) is a spaceborne scatterometer which flew aboard the National Space Development Agency of Japan's ADvanced Earth Observing Satellite (ADEOS). Although the three year mission was cut short due to failure of the spacecraft solar array, NSCAT returned over 9 months of observations of the Earth. NSCAT was originally designed to measure winds over the ocean; however, it...

An Algorithm to Assess the Accuracy of NASA Scatterometer Data - Geoscience and Remote Sensing Symposium Proceedings, 1998. IGARSS '98. 1998 IEEE International

A simple wind field model can be used to evaluate the accuracy of pointwise ambiguity removal for NASA Scatterometer (NSCAT) data. Errors in pointwise ambiguity removal result in large model-fit errors when the pointwise wind estimates are assimilated into the model. By thresholding the error, regions containing ambiguity removal error can be identified. For many of these regions, the ambiguity...

Azimuth variation in microwave backscatter over the Greenland ice sheet - Geoscience and Remote Sensing Symposium, 2001. IGARSS '01. IEEE 2001 International

Scatterometer backscatter measurements are becoming an important tool for monitoring the dynamic behavior of the Greenland ice sheet. However, most Greenland studies assume constant backscatter for varying azimuth angles. Detailed analysis of scatterometer data sets show non-negligible (1-2 dB) azimuth modulation. The magnitude and orientation of the azimuth modulation observed by SeaWinds, NSC...
