py-sonde-comparison(NPO-52559-1)

The program is three core elements, described below: 1) read_product: This method reads satellite data products, which will be modified as new groups are included in the analysis. Key elements extracted are lat/lon, ozone profiles and aprioris and averaging kernels. 2) colocate: This methods takes the data from read_product, and uses the WOUDC ozonesonde extraction tool pywoudc to extract ozonesonde data within the same timeframe as the satellite data. The lat/lon and timestamps of satellite data are compared with those of the ozonesondes, if matches are found within a certain tolerance, these locations are saved, and output as a separate datafile. 3) plot_results: This method takes the files saved in colocate and performs statistical analysis and plots the results for further analysis and discussion. The code will evolve as additional satellite retrieval groups are added, and additional analysis tools are required.
