A analysis workforce co-led by a scientist from Auburn College is the primary to check and report strategies for calculating cover cowl from the Ice, Cloud, and Ice Elevation Satellite tv for pc 2. NASA Earth, or ICESat-2.

A part of NASA’s Earth Commentary System, ICESat-2 is a satellite tv for pc mission to measure ice sheet elevation and sea ice thickness, in addition to land topography, vegetation and clouds.

In a latest examine revealed within the journal “Distant Sensing of Atmosphere”, the workforce, co-led by Lana Narine, assistant professor of geospatial evaluation on the School of Forestry, Wildlife and Atmosphere, investigated strategies for deriving the protection of the cover and characterize the predictive capability, with ICESat-2.

Though a essential forest biophysical attribute, cover cowl isn’t but reported by ICESat-2, and the final cover cowl product for the contiguous United States is from 2016. It’s due to this fact crucial to higher perceive the appliance of ICESat-2. to offer info on cover cowl and to doubtlessly contribute to an up to date cover cowl product.

“Cover cowl is a basic attribute of forest vegetation construction that’s used to outline a forest and help a spread of functions, together with assessing forest degradation, estimating the suitability of habitat and above-ground biomass characterization,” Narine mentioned.

Funded by a NASA ICESat-2 science workforce, research with an ICESat-2 grant, the challenge demonstrated the potential for software of freely accessible Earth commentary information supplied by the ICESat- 2 to derive the cover cowl.

Utilizing photon counting mild detection and ranging information from ICESat-2 and vegetation product information from the mission, the examine centered on two forested areas within the southern United States, the Sam Houston Nationwide Forest, or SHNF, in southeast Texas and the Solon Dixon Forestry Schooling Middle, or SDFEC, in southern Alabama.

The targets of the examine have been to develop and consider equations estimating cover cowl with ICESat-2 and to guage a model-based strategy to enhance the estimates.

“Integrating information from a space-based mild detection and ranging instrument like ICESat-2 provides a novel alternative to combine structural details about vegetation at massive spatial scales,” mentioned Janaki Alavalapati, Dean of the School of Forestry, Wildlife and the Atmosphere.

Ongoing collaborative efforts by Narine and co-authors Sorin Popescu and Lonesome Malambo of Texas A&M College will embody the event of a gridded cover protection product utilizing ICESat-2.
