Accessing NMDB data using NEST and pandas

The Neutron Monitor database (NMDB) was created by teams from 12 different countries in 2008. Data from neutron monitors worldwide is pooled and made available, for many stations in real-time. The NMDB Event Search Tool (NEST) started as a quick-look interface to the data in NMDB, but by now has become the main interface to all NMDB data. NEST does not only enable you to plot data from one or several NMDB stations in a very customizable way, it also allows you to retrieve the data in ASCII format for further processing or creating your own plots. Downloading data can be scripted using ‘wget’ or ‘curl’ as documented in ‘3 ways 2 use NEST’. Here we are presenting python functions to read in data from one or several stations directly from NEST into a pandas dataframe. Once your data is in a ‘dataframe’, you can easily sort, modify or plot data with python.
