China CO2 Terra NDVI

Coupling the Annual Atmospheric CO2 Cycle to Satellite NDVI

November 20, 2018 in Animation, Carbon dioxide, China, CO2, NDVI, Remote sensing, United States

The annual seasonal cycle in atmospheric CO2 concentrations is well known, largely attributable to the preponderance of mid-latitude, terrestrial vegetation in the northern hemisphere compared to the southern hemisphere. When northern hemisphere vegetation is photosynthetically active, which roughly corresponds with emergence through reproduction and primarily occurs during May-September, atmospheric CO2 is consumed and its concentration declines. Conversely, when northern hemisphere vegetation is senescing or dormant, atmospheric CO2 levels increase. By analogy with organismic respiration, this oscillatory behavior is sometimes described as the Earth “breathing.”

We created two animations illustrating the relationship between CO2 and terrestrial photosynthesis using the famous

Kansas Statewide 2-m LiDAR

March 14, 2018 in Elevation, Kansas, LiDAR, Remote sensing, Shaded Relief

In 2005-2006, the state of Kansas began development of its LiDAR bare-earth elevation dataset with a 2-m resolution coverage along the Kansas River corridor and several adjacent counties. Over the course of the next decade, piece-by-piece, statewide coverage was eventually achieved. Data specifications improved along the way, so that most of the bare-earth raster data (referred to as digital terrain models, or DTMs) are available at 1-m resolution and have been subjected to hydro-flattening, whereby the water surfaces of many waterbodies and large streams have been given a smooth representation to facilitate hydrologic and hydraulic processing. New collections are underway ...

Soy next to forest in Mato Grosso, Brazil

Mato Grosso Land Cover

June 14, 2017 in Agriculture, Amazon, Cerrado, Cotton, Deforestation, Intensification, Land Cover Mapping, Land Use Change, Mato Grosso, MODIS, NDVI, Remote sensing, Soybeans, Sugarcane

Mato Grosso is a frontier in the sense that natural vegetation, both rainforest and savanna, known as cerrado, are being replaced with crop production and other agricultural uses. Mechanized agriculture moved rapidly into the area in the 1990s, with soybeans the dominant crop. Since then, crop production increases have come about through both cropland expansion (horizontal intensification) and a transition from predominantly single-cropping to mostly double-cropping (vertical intensification). In July 2006, the Soy Moratorium was implemented with the purpose of reducing Amazon deforestation for the purpose of soy production.

Western Governors' Association Crucial Habitat Assessment Tool, 2013

KU and KBS are key partners in creation of new West-wide Crucial Habitat service

For the last three years, the Western Governors Association (WGA) has been working with state wildlife agencies to create a standardized map of Crucial Habitat across the western United States to inform energy, transportation, and land use planning decisions at a regional scale. A collaborative effort of this scope between state wildlife agencies has not been accomplished before, and this effort represents a huge step forward in identifying landscapes that provide important resources to wildlife.

Two units of the Kansas Biological Survey at the University of Kansas worked closely with the Kansas Department of Wildlife, Parks and Tourism (KDWPT) ...
