The Inter-mission Time Series of Land Ice Velocity and Elevation (ITS_LIVE) project has a singular mission: to accelerate ice sheet and glacier research by producing globally comprehensive, high resolution, low latency, temporally dense, multi-sensor records of land ice and ice shelf change while minimizing barriers between the data and the user.
ITS_LIVE data currently consists of NetCDF Level 2 scene-pair ice flow products posted to a standard 120 m grid derived from Landsat 4/5/7/8/9, Sentinel-2 optical scenes, and Sentinel-1 SAR scenes. We have processed all land-ice intersecting image pairs separated by ≤546 days for optical and ≤12 for SAR sensors, for all missions from each mission start to the end of 2022.
The ITS_LIVE project will continue processing new optical and radar scene pairs as they come in, and will soon increase production to include SAR image pairs separated by more than 12 days. We also expect to extend processing to include ASTER, RADARSAT, and NISAR imagery[...]

We also expect to extend processing to include ASTER, RADARSAT, and NISAR imagery. Further, all scene pair data are combined into a set of Zarr datacubes that are cloud-optimized for time-series analysis, with a suite of user tools available to query the data effectively. The ITS_LIVE project is also producing a suite of Level 3 products, including quarterly and annual ice-sheet and regional velocity mosaics as Cloud-Optimized GeoTIFFs, standardized records of elevation change rates for Greenland and Antarctica, and ice shelf and tidewater glacier front positions.

The Japan Aerospace EXploration Agency (JAXA) SELenological and ENgineering Explorer (SELENE) mission’s Kaguya spacecraft was launched on September 14, 2007 and science operations around the Moon started October 20, 2007. The primary mission in a circular polar orbit 100-km above the surface lasted from October 20, 2007 until October 31, 2008. An extended mission was then conducted in lower orbits (averaging 50km above the surface) from November 1, 2008 until the SELENE mission ended with Kaguya impacting the Moon on June 10, 2009. These data are digital terrain models derived using the NASA Ames Stereo Pipeline (ASP) and the Kaguya stereoscopic data. Digital terrain models (DTMs) in this data set were bundle adjusted and aligned to Lunar Orbiter Laser Altimeter (LOLA) shot data. The sensor model intrinsics used for these data have been re-estimated to reduce inter-DTM horizontal and vertical errors. Data are controlled to LOLA using the ASP pc_align program.
