Determining the daily temperature range

The daily temperature range, or diurnal temperature variation as it is called in meteorology, is not so big a deal on Earth. In desert areas on Earth or generally on different planets, the variation is greater. We will have a look at the daily temperature range for the data we downloaded in the previous example:

1. To analyze temperature ranges, we will need to import the NumPy package and the NumPy masked arrays:

   import numpy as np
   import sys
   import numpy.ma as ma
   from datetime import datetime as dt

2. We will load a bit more data than that loaded in the previous section: dates of measurements in the YYYYMMDD format and the average daily temperature. Dates require special conversion. Firstly date strings are converted ...
