Developing an annual land surface temperature from 1985 to present for select international sites: First Outputs Developing an annual land surface temperature from 1985 to present for select international sites: First Outputs
Surface Urban Heat Island (SUHI) land surface temperature (LST) data is derived from Landsat thermal band. The LST including annual mean LST (MeanLST) and annual maximum LST (AVEMaxLST). The annual mean LST (MeanLST) therefore represents the average of all clear observations in a specific year. The seasonal maximum temperatures were then averaged to represent the annual mean maximum LST...
Annual National Land Cover Database (NLCD) Collection 1.0 Validation Tables Annual National Land Cover Database (NLCD) Collection 1.0 Validation Tables
A validation assessment of Annual National Land Cover Dataset (NLCD) CONUS Collection 1.0 annual land cover products (1985–2023) for the Conterminous United States (CONUS) was conducted with an independently collected reference dataset. Reference data land cover attributes were assigned by trained interpreters for each year of the time series (1984–2023) to a reference sample of 8,360...
Annual National Land Cover Database (NLCD) Collection 1.0 Reference Data Product Annual National Land Cover Database (NLCD) Collection 1.0 Reference Data Product
This Annual NLCD Reference Data Product includes the collection of an independent dataset of 8,360 30-meter by 30-meter samples across the Conterminous United States (CONUS). The Annual NLCD Collection 1 sample design was developed as a two-phase collection by a team of image interpreters as follows: an initial base sample containing 5,000 sample plots chosen purely by simple random...
Lake trout egg catch per unit effort (CPUE) estimates at Stony Island Reef, 2017, 2019 Lake trout egg catch per unit effort (CPUE) estimates at Stony Island Reef, 2017, 2019
This data set contains Lake Trout (Salvelinus namaycush) egg catch per unit effort (CPUE) estimates obtained from egg traps set on Stony Island Reef in Lake Ontario. These data were collected from sampling efforts in November 2017 and October-November 2019. Stony Island Reef is a cobble spawning reef located in the eastern basin of Lake Ontario and was chosen as the study site because it...
Upper Mississippi River System Changes in Floodplain Inundation from 1940 to 2022 Upper Mississippi River System Changes in Floodplain Inundation from 1940 to 2022
Floodplain inundation is believed to be the dominant physical driver of an array of ecosystem patterns and processes in the Upper Mississippi River System (UMRS). Here, we present results of a change analysis to estimate shifts in floodplain inundation regime characteristics from 1940 to 2022 in navigation pools 3 through 10 along the Upper Mississippi River. Data were derived from a...
