Case Study: Numerical Convergence Study on Simulated Spaceborne Microwave Radiometer Measurements of EarthThis paper describes a NASA case study the outcome of which can be implemented in aclassroom setting. Through this case study students can learn numerical interpolation andintegration of functions in space as well as the error analysis. A tradeoff expected to be observedis between the speed of obtaining results and getting accurate results. As a result,recommendations are expected for various data sets to ensure fast accurate results. Thesimulation can also be carried out using Matlab.The case study discusses numerical convergence of simulated space-borne microwaveradiometer measurements of Earth brightness temperatures so as to get fast results. The resultsare obtained by numerically evaluating a double integral. The integral relies on antenna patternmeasurements and observed brightness temperature distribution over the Earth’s surface.Accurate antenna temperatures are obtained by modifying the step sizes while getting fasterresults. The accuracy of the numerical methods is analyzed and recommendations are given toimprove the process. Such recommendations will be seen to vary for different data patterns. Thestudy will also include antenna theory to understand its parameters, and antenna equations thataffect the accuracy of the results as well as Antenna Equipment, Radiation patterns and radiationpropagation.
