| Summary: | <p>GPS interferometric reflectometry (GPS-IR) is a technique
that can be used to measure snow accumulation on ice sheets. The footprint
of the method (<span class="inline-formula">∼1000</span> m<span class="inline-formula"><sup>2</sup></span>) is larger than that of many
other in situ methods. A long-term comparison with hand measurements yielded
an accuracy assessment of 2 cm. Depending on the placement of the GPS
antenna, these data are also sensitive to firn density. The purpose of this
short note is to make public GPS-IR measurements of snow accumulation for
four sites in Greenland, compare these records with in situ sensors, and
make available open-source GPS-IR software to the cryosphere community.</p> |
