Airborne laser ice surface height and slope (IceBridge)

IceBridge ATM L2 Icessn Elevation, Slope, and Roughness V002
atmosphere NASA NSIDC_CPRD Level 2 ASCII
In plain English

What it measures. Smoothed measurements of how high the ice surface is, plus how steep (slope) and bumpy (roughness) it is, over Arctic and Antarctic sea ice and the ice sheets of Greenland and Antarctica.

How it's made. Collected by a laser-mapping instrument (the Airborne Topographic Mapper) flown on research aircraft during NASA's Operation IceBridge campaigns, then resampled and smoothed.

How & where you'd use it. Supports studies of how ice thickness and surface shape change, helping bridge gaps between satellite missions and track ice loss.

Official description

This data set contains resampled and smoothed elevation measurements of Arctic and Antarctic sea ice, and Greenland, Antarctic Peninsula, and West Antarctic region land ice surface acquired using the NASA Airborne Topographic Mapper (ATM) instrumentation. The data were collected as part of Operation IceBridge funded aircraft survey campaigns.
