Note:

This code-base is no longer being maintained in this repository solely by Dr. Mike MacFerrin. It is being maintained and further developed at the National Snow & Ice Data Center (NSIDC) with Dr. MacFerrin and co-workers at their Antarctica Today repository: https://github.com/nsidc/Antarctica_Today/ This code contained here has been deprecated.

Antarctica_Today

The "Antarctica Today" code and datasets necessary to create the database, update it, and generate plots and maps of results.

Directories:

/baseline_datasets/ Datasets necessary for data generation, including the ice mask and region-area masks.

/data/ -- Storing all derived data products. (Source data from NSIDC is stored in the /Tb/ directory.)

/data/annual_sum_geotiffs/ -- GeoTiff files of the annual sum of melt days over the continent.

/data/gap_fill_data/ -- Data of computed mean climatologies used to fill missing gaps early in the datasets (especially in the 1980s), as well as occasional missing days/values in recent datasets.

/data/mean_climatology/ -- Data for comuting the mean climatologies.

/data/thresholds/ -- The annual Tb-threshold files (from Mote, et al.), delineating the threshold above which melt is nominally detected in the 37H microwave brightness temperatures.

/plots/ -- Directories for placing output line plots and maps.

/plots/annual_maps_sum/ -- After each melt season is finished, annual maps of the sum of melt days are generated and put here.

/plots/annual_maps_anomaly/ -- Annual maps of the anomaly from baseline averages of melt days.

/plots/annual_line_plots/ -- Annual line graphs of melt compared to the baseline data period (1990-2020).

/plots/daily_maps/ -- A place to put the daily-generated melt maps (empty for now).

/Tb/ -- Raw NSIDC Tb datasets (nsidc-0080, etc)

/qgis/ -- QGIS project that includes these datasets, for viewing. Also the vector Antarctica outline (from Quantarctica) for viewing and creating export maps.

/qgis/basemap_picklefiles/ -- A place to cache pickled versions of the basemaps. This increases efficiency of generating new basemaps with data plotted atop them.

/qgis/basins/ -- Shapefiles of the basin outlines (for generating maps).

/src/ -- Source code.

/src/conf_int/ -- utilities for generating confidence intervals and prediction intervals on long-term trend lines.

/src/src_baseline/ -- Source code used for generating the baseline datasets needed for the Antarctica Today dataset (namely, the gridded elevation, ice mask, and average annual temperature datasets).
