Scientists blog from Antarctica and provide a glimpse of what it's like to do research in the field. 
What's hot in the news around climate and sea ice and what are scientists talking about now? On Wednesday, January 26 from 9:00 a.m. to 1:00 p.m. (USA Mountain Time), the following data collections may not be available due to planned system maintenance: AMSR-E, Aquarius, High Mountain Asia, IceBridge, ICESat/GLAS, ICESat-2, MEaSUREs, MODIS, NISE, SMAP, SnowEx, and VIIRS.
Data Set ID:
ILATM2
IceBridge ATM L2 Icessn Elevation, Slope, and Roughness, Version 2
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.
This is the most recent version of these data.
Version Summary:
The Version 2 data are in Comma Separated Value (CSV) ASCII format. A header has been added to the Version 2 data format. In Version 1, the data set consisted of pairs of files for each data segment: one data file and one summary file. The header of the Version 2 data file contains information that had appeared in the summary file, making the summary file redundant.
COMPREHENSIVE Level of Service
