Modelling vegetation phenology at six field stations within the U.S. Great Plains: constructing a 38-year timeseries of GCC, VCI, NDVI, and EVI2 using PhenoCam imagery and DAYMET meteorological records Open
Vegetation phenology models still rely on temperature as the primary limiting factor to growth. They generally do not recognize the importance of photoperiod and water availability, which can cause them to under-perform. Moreover, few mode…
Mission to earth: LANDSAT 9 will continue to view the world Open
The global Earth Observations, remote sensing, geoscience, environmental and applied science communities celebrated the successful launch of LANDSAT 9 on Sept. 27, 2021. LANDSAT 1 (originally named...
Semi-Automatic Fractional Snow Cover Monitoring from Near-Surface Remote Sensing in Grassland Open
Snow cover is an important variable in both climatological and hydrological studies because of its relationship to environmental energy and mass flux. However, variability in snow cover can confound satellite-based efforts to monitor veget…
<i>Geocarto International’s</i> on-going long-term mission to publish research on Earth Observations and GIS: our notable contributions to Sustainability Development Goals of the United Nations 2030 Agenda for Sustainable Development Open
During our long history of 35 years of publication, Geocarto International’s primary mission has been to publish research focused on Earth observations and GIS with an emphasis on disseminating thi...
An exploration of colorectal cancer incidence rates in North Dakota, USA, via structural equation modeling Open
Well water contains several agents, e.g., bacteria, disinfection by-products, and nitrates that are potent colorectal carcinogens. Studies of well water use and colorectal cancer risk at the individual level in North Dakota are warranted.

Monitoring Landscape Dynamics in Central U.S. Grasslands with Harmonized Landsat-8 and Sentinel-2 Time Series Data Open
Remotely monitoring changes in central U.S. grasslands is challenging because these landscapes tend to respond quickly to disturbances and changes in weather. Such dynamic responses influence nutrient cycling, greenhouse gas contributions,…
Seasonal home ranges and habitat selection of three elk (Cervus elaphus) herds in North Dakota Open
Changes in land use have resulted in range shifts of many wildlife species, including those entering novel environments, resulting in the critical need to understand their spatial ecology to inform ecosystem effects and management decision…
Detection of Shelterbelt Density Change Using Historic APFO and NAIP Aerial Imagery Open
Grand Forks County, North Dakota, boasts the highest concentration of shelterbelts in the World. As trees age and reach their lifespan limits, renovations should have taken place with new trees being planted. However, in recent years, the …
County level incidence rates of chronic lymphocytic leukemia are associated with residential radon levels Open
CLL is significantly associated with RR at the county level.
Geographic distributions of motor neuron disease mortality and well water use in U.S. counties Open
These findings support the hypothesis that an agent present in well water plays an etiologic role in ALS. Further study of water use among individuals with ALS is warranted.
A topographic framework for estimating spatial variation in hill country grasslands Open
Livestock graze hill country regions worldwide where grassland biomass or structure is important both economically as forage and enviromentally as habitat for wildlife. Manual measurements of biomass in remote and expansive hill country la…
