Question

https://coastwatch.glerl.noaa.gov/ftp/glsea/avgtemps/2020/glsea-temps2020_1024.datIt is up to you to extract the data from the file and put it into MATLAB. 

This operation must be done with MATLAB! Do not copy and enter data by hand! You are to make a report showing tables, graphs and conclusions based on data using MATLAB functionality. Required elements: The entire project must be presented as one single script file . Divide your codes into sections, one for each question, and add text comments to identify which question is answered in that section. To create a section add a comment that begins with %%. To learn more about sections and how to create and use them, you can search for 'Create and Run Sections in Code' in the MATLAB help. All computations to be done in MATLAB using the imported data file. Nothing can be done by hand. 1. Calculate the yearly average temperature for each of the lakes, and the yearly average for all six lakes put together. 2. Indicate which lake is the coldest and which one is the warmest, based on the average yearly temperatures calculated in step #1. Also indicate which lakes have average temperatures above the average of all the lakes and which ones are below that same average. 3. Indicate the day and the temperature for the warmest water temperatures for each of the lakes. Do the same for the coldest temperatures. In the case of a tie, mention all the dates. 4. Indicate the day, lake and temperature of the warmest water temperature overall. Do the same for the coldest temperature. In the case of a tie, mention all the dates. 5. Make a graph of the temperature of each daily average (x=day, y=temp). Make one graph per lake to show the yearly temperature trends. Label the axes clearly and add titles to all your graphs. Use script commands to generate the labels and titles for all graphs. 6. Make a single graph of the temperatures (x=day, y=temp) that shows all 6 lines on one graph. Each lake will have a different colour and line type. Title your graph, label your axes, and have a legend. 7. Calculate the summer average (day 172 to day 265) for all 6 lakes (one average per lake). Is the order from warmest to coldest the same as with the yearly average calculated in step #1? 8. Make a graph for summer days only (day 172 to day 265) with all 6 lakes on one graph. Title your graph, label your axes and have a legend (use the same colours, line types, and legend as the graph you made in step #6). 9. Calculate the winter average (days 1 to 79 and days 355 to 365) for all 6 lakes (one average per lake). Is the order from warmest to coldest the same as with the yearly average calculated in step #1? 10. Make a graph for winter days only (days 1 to 79 and days 355 to 365) with all 6 lakes on one graph. Title your graph, label your axes, and have a legend (use the same colours, line types and legend as the graph you made in step #6). 11. Assuming that you can swim comfortably in the lake if the temperature is above 20 degrees, calculate the number of days in the year you can swim for each of the 6 lakes. Make pie charts of the percentages of total days of the year that you can swim in the lakes. Make one pie chart per lake and put all 6 on the same figure. Indicate each lake clearly next to the pie chart in the figure. 12. Assuming that lakes freeze when the water falls below 0 degrees. Calculate the number of days in the year that the lake is frozen. You must calculate the number of days with MATLAB, even if you know that there are none. Your program should work for years that would have some. 13. Re-do question 1 (the 7 yearly averages) but with data from 2019 instead. Make a table of the averages side by side to illustrate the two yearly results. Any notable changes between 2019 and 2020? Can you advance a conclusion why there is a difference (or not)? The data file for 2019 is here:
