We computed the EOFs using the equatorial sea surface temperature and saw that the first mode looks similar to the pattern we are familiar with. This first mode has its own time series, and we wonder what frequency contributes to the data the most. Apply the procedure for the power spectrum to the time series of the first mode. »

A confidence interval of monthly mean precipitation In the class, we learned how to compute the 95% confidence interval for a population mean. Using this method, try to estimate the 95% confidence interval for the monthly mean precipitation. Since we do not know the population standard deviation of the monthly mean precipitation, we have to use the sample standard deviation. In this case, the confidence interval can be estimated using t-distribution. »

A close look at the Keeling Curve Accurately measuring CO$_2$ in the atmosphere requires lots of effort and support. It is unfortunate that there were years without financial support in the early period of this program and David Keeling couldn’t make measurements. This is shown in the dataset! You can see that some of the entries of CO$_2$ concentration are $-99.99$. Considering that this dataset contains concentration values, the negative entry doesn’t make sense. »

Create weather forecast Using weather data from KMA, write a code to produce weather outlook/statement that looks like the section, “Detailed Forecast” in NWS. Pick a region you want to make forecast. In addition to max/min temperature, please add a statement that compares it with the climatological values. Try to create your own class to do this job. Turn in the python file or jupyter notebook file by next Thursday. »

Take street address of Yonsei University (50 Yonsei-ro, Seodaemun-gu, Seoul 03722, Republic of Korea) and create a dictionary myaddress. Create a variable full_address that is the concatenation of all the elements of the myaddress variable by placing commas and blank spaces as needed. Using iteration, print out the full address. »
