The data comes from the U.S. International Air Passenger and Freight Statistics Report. As part of the T-100 program, USDOT receives traffic reports of US and international airlines operating to and from US airports. There are two datasets available:
Each observation provides information on a specific airline for a pair of airports, one in the US and the other outside. Three main columns record the number of flights: Scheduled, Charter, and Total.
U.S. International Air Passenger and Freight data are confidential for a period of 6 months, after which it can be released. As a result, quarterly reports and the year to date/calendar year raw data files available here will always lag by two quarters.

site suitability criteria included in the techno-economic land use screens are
listed below. As this list is an update to previous cycles, tribal lands, prime
farmland, and flood zones are not included as they are not technically
infeasible for development. The techno-economic site suitability exclusion
thresholds are presented in table 1. Distances indicate the minimum distance
from each feature for commercial scale wind development

The site suitability criteria included in the techno-economic land use screens are listed below. As this list is an update to previous cycles, tribal lands, prime farmland, and flood zones are not included as they are not technically infeasible for development. The techno-economic site suitability exclusion thresholds are presented in Table 1. Distances indicate the minimum distance from each feature for commercial scale solar development.
Attributes:
Steeply sloped areas: change in vertical elevation compared to horizontal distance
Population density: the number of people living in a 1 km2 area
Urban areas: defined by the U.S. Census.8
Water bodies: defined by the U.S. National Atlas Water Feature Areas, available from Argonne National Lab Energy Zone Mapping Tool9
Railways: a comprehensive database of North America's railway system from the Federal Railroad Administration (FRA), available from Argonne National Lab Energy Zone Mapping Tool
Major highways: available from ESRI Living Atlas10
Airports: The Airports dataset including other aviation facilities as of July 13, 2018 is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics' (BTS's) National Transportation Atlas Database (NTAD). The Airports database is a geographic point database of aircraft landing facilities in the United States and U.S. Territories. Attribute data is provided on the physical and operational characteristics of the landing facility, current usage including enplanements and aircraft operations, congestion levels and usage categories. This geospatial data is derived from the FAA's National Airspace System Resource Aeronautical Data Product. Available from Argonne National Lab Energy Zone Mapping Tool
Active mines: Active Mines and Mineral Processing Plants in the United States in 200311
Military Lands: Land owned by the federal government that is part of a US military base, camp, post, station, yard, center or installation.
