Satellite sensors can be used to measure many different pieces of information that help us understand more about the atmosphere. It is composed of a number of layers around the earth. A satellite experiment was launched on the NIMBUS 7 spacecraft in 1978 to collect data on the composition and structure of the middle atmosphere. The instrumentation and sensors collected data from October 25, 1978, to May 28, 1979, returning more than 7,000 sets of data to the earth each day. These data were used to determine temperature, ozone, water vapor, nitric acid, and nitrogen dioxide distributions in the stratosphere and mesosphere.
Consider a problem in which we have collected a set of data measuring the ozone-mixing ratio in parts per million volume (ppmv). Over small regions, these data are nearly linear, and thus we can use a linear model (mixing ratio = slope * altitude + intercept) to estimate the ozone at altitudes other than ones for which we have specific data. Write a program that reads a data containing the altitude in km and the corresponding ozone mixing ratios in ppmv in the form x1 y1, x2 y2, …, xn yn for a region over which we want to determine a linear model. Use the least-squares technique presented below to determine and print the model. Also, print the beginning and ending altitudes to indicate the region over which the model is accurate.
