Surface Mass Balance and Snow Depth on Sea Ice Working Group (SUMup) accumulation on land ice subdataset

This dataset includes accumulation on land ice measurements from both hemispheres. This
dataset is a community effort to distribute easy to use in-situ data to improve surface mass
balance modeling and remote sensing efforts. This dataset is a compilation of work from many
individual researchers. When using this dataset please cite both the individual researchers who
provided the data as listed in the Citation field as well as this dataset. The snow accumulation
on land ice subdataset contains over 230,000 data points. The Arctic accumulation
measurements, all within Greenland, contain 62% of the measurements with ~1% coming from
Summit Station. The Antarctic contains the remaining 38% of the measurements. While most of
the data are measurements of accumulation between 1950 and present (~98%), to coincide
with the time span of many regional climate models and reanalysis products, some records
(~2%) are included dating back to 1800. The measurement methods include ice cores, snow
pits, radar isochrons, and stake measurements. Fields of data include the date taken, latitude,
longitude, start year and end year (if not an annual measurement), year (if annual),
accumulation, error, elevation, radar horizontal resolution, method, name of field campaign,
and associated citation.
