Aeroecology focuses "on the planetary boundary layer, or aerosphere, and the myriad of organisms that, in large part, depend upon this environment for their existence" (Kunz et al. 2008). The primary mission of the Aeroecology Community is to act as a clearing house for remotely sensed data related to biological use of the aerosphere. This community aims to provide biological data collected from weather radar, portable radar, thermal imaging, and other applicable and emerging technologies.
This WSR-88D weather radar dataset includes different types of scatterers hand-screened and identified based on a combination of scientific literature and media reports of biological events, knowledge of animal natural history in confirming radar sweeps characterized by a given type, and a re-evaluation and subsampling process to avoid inclusion of non-focal types. The dataset is comprised of eight scatterers, seven biological and one meteorological: trans-gulf migrants, purple martins (Progne subis), waterfowl and sandhill cranes, black-necked grebes (i.e., eared grebe, Podiceps nigricollis), Brazilian free-tailed bats (Tadarida brasiliensis), diurnal insects, mayflies and midges, and precipitation. This dataset...
The U.S. network of 160 weather radars known as NEXRAD (NEXt generation RADar) is one of the largest and most comprehensive terrestrial sensor networks in the world. To date, the National Climatic Data Center (NCDC) has archived about 2 petabytes data from this system. Although designed for meteorological applications, these radars readily detect the movements of birds, bats, and insects. Many of these movements are continental in scope, spanning the entire range of the network. It is unclear whether biological or meteorological data comprise the bulk of the archive. Regardless, the biological portion is sufficiently large that it likely represents one of the largest biological data archives in the world, perhaps...

Yellow sweet clover (Melilotus officinalis; clover hereafter) is a biennial legume native to Eurasia that is now present in all 50 states. Clover can grow 2 m tall and achieve high densities across large areas in the Northern Great Plains when conditions are conducive, such as in 2019. Clover is highly efficient at fixing nitrogen in soils which reduces the abundance of native grasses, while simultaneously facilitating invasion of non-native grasses, which may alter fire regimes. In contrast, clover provides considerable forage for ungulates, attracts a wide variety of insects that, along with clover seeds, are important to waterfowl, gamebirds, and songbirds, and supports numerous pollinators. Little is known about...
There are 12 composite NEXRAD images included in this Science Base item, with four images each for hurricanes Katrina, Rita, and Wilma. The four images for each storm are labeled as: StormName_Reflectivity_High, StormName_Reflectivity_Low, StormName_Radial_Velocity_High, and StormName_Radial_Velocity_Low. Reflectivity and radial velocity refer to the moment (type of data) collected by the NEXRAD radars, with reflectivity measuring the overall strength of the radar signal and radial velocity measuring the velocity of the target with respect to the radar. High and Low refer to the operating angle of the NEXRAD radars with high being the closest angle to 3.5 degs and low being the closest angle to 0.5 degs for each...
This Science Base item contains three file geodatabases (Katrina_Radar_Data, Rita_Radar_Data, and Katrina_Radar_Data), a symbology folders with two layer files (Radial_Velocity_scale and Reflectivity_scale, as well there associated shapefiles), and a single metadata document (Composite_NEXRAD_Metadata in three formats: .xml, .txt, and .html) that covers all the data in the three geodatabases. Each geodatabase contains data (if available) compiled from 94 NEXRAD stations in the eastern half of the U.S. collected at approximately 0300 UTC on the day these three hurricanes made landfall: 8/29/2005 - Katrina, 9/24/2005 - Rita, and 10/24/2015 - Wilma. There are four feature classes within each geodatabase: StormName_Reflectivity_High,...
