Google Earth Engine (GEE) - Compute monthly daytime and nighttime Monthly Land Surface Temperature (LST) image averages and download using the "MODIS/061/MOD21C3" product

Use the "MODIS/061/MOD21C3" product to calculate the average of the monthly daytime and nighttime Land Surface Temperature (LST) images, here we need to traverse, then set a temperature conversion, then set the month and copy the properties of the original code. Then we can also add month-by-month images on the map. Here is an important function to know:

setMulti() This is when adding multiple remote sensing attributes to the band, here it needs to be added according to the dictionary type.

ee.Date.fromYMD(year, month, day, timeZone)
Returns a Date given year, month, day.

Arguments:
year (Integer)
month (Integer)
