mlampros/icesat2r repository overview

⁠IceSat2R

Programmatic connection to the OpenAltimetry API⁠ to download and process the following ICESat-2 Altimeter Data,

• 'ATL03' (Global Geolocated Photon Data)
• 'ATL06' (Land Ice Height)
• 'ATL07' (Sea Ice Height)
• 'ATL08' (Land and Vegetation Height)
• 'ATL10' (Sea Ice Freeboard)
• 'ATL12' (Ocean Surface Height)
• 'ATL13' (Inland Water Surface Height)

The user has the option to download the data by selecting a bounding box from a 1- or 5-degree grid globally utilizing a shiny application.

The ICESat-2 mission collects altimetry data of the Earth's surface. The sole instrument on ICESat-2 is the Advanced Topographic Laser Altimeter System (ATLAS) instrument that measures ice sheet elevation change and sea ice thickness, while also generating an estimate of global vegetation biomass.

ICESat-2 continues the important observations of

• ice-sheet elevation change
• sea-ice freeboard, and
• vegetation canopy height

begun by ICESat in 2003.

System Requirements:

The usage of the IceSat2R package requires a geospatial setup as specified in the sf⁠ or terra⁠ README.md files.

⁠3-Dimensional Line Plot by combining IceSat-2 and Copernicus DEM (Digital Elevation Model) Data

The following 3-dimensional interactive line plot (which appears in the 'IceSat-2_Atlas_products' Vignette⁠) shows,

• in blue color the elevation based on the DEM compared to the two ICESat-2 beams ('gt1r' and 'gt2l'), as these are separated by a 3-km distance
• in orange color the land-ice-height measurements of the summer period (separately for 'gt1r' and 'gt2l')
• in green color the land-ice-height measurements of the winter period (separately for 'gt1r' and 'gt2l')

To install the package from CRAN use,

install.packages("IceSat2R")

and to download the latest version of the package from Github,

remotes::install_github('mlampros/IceSat2R')
