Tri-County Regional Airport (Spring Green) is an airport with the ICAO code KLNR and the IATA code LNR. Country: United States. Nearest settlement listed in the database: Spring Green. OurAirports classifies it as a small airport. Its ICAO code starts with the KL prefix, which marks airports in United States. The four-letter code KLNR is used in flight operations and weather reports, while the three-letter IATA code LNR is used for ticketing and baggage handling. The airport reference point sits at 43°12'36"N, 90°10'53"W, at an elevation of 717 ft (219 m) above sea level. The applicable time zone is America/Chicago.

The course is derived from the runway designator (number × 10), not from a survey - the actual magnetic bearing can differ by a few degrees.
Declared distances (TORA, TODA, ASDA, LDA) are published in the national AIP - they are not part of this table.
According to OurAirports data (compiled from AIP and FAA sources), Tri-County Regional Airport (Spring Green) has 2 runways: 09/27 - 1,524 m long (5,000 ft), 23 m wide, asphalt surface; 18/36 - 564 m long (1,850 ft), 18 m wide, asphalt surface.
The longest of them is 09/27, at 1,524 m.
The thresholds are oriented as follows: 09/27 on 90° and 270° magnetic, 18/36 on 180° and 360° magnetic. A threshold designator is its magnetic heading divided by ten (ICAO Annex 14), so the runway axis can be read straight off the numbers.
For the 09/27 axis, wind from the south (around 180°) or from the north (around 360°) blows perpendicular to the runway and produces the largest crosswind component. Wind from around 90° or 270° acts along the runway, as a headwind or a tailwind. The decoder on this page computes those components automatically from the current METAR.
Weather reports for Tri-County Regional Airport (Spring Green) are published under the ICAO code KLNR. A METAR is an observation of current conditions, usually issued every 30 or 60 minutes; a TAF is a forecast for the airport area, typically covering 9 to 30 hours.
The decoder breaks the KLNR report down into its parts: wind direction and speed including gusts and variability, visibility (including CAVOK and directional minimum visibility), weather phenomena by WMO code, cloud layers with their bases, temperature and dew point, QNH pressure, and the resulting flight category - VFR, MVFR, IFR or LIFR - using FAA thresholds.
Not every airport issues its own reports; many smaller airfields have no weather station. If no current data is available for KLNR, check the nearby airports listed below.
Reports always use UTC (the Z suffix). The America/Chicago zone is GMT-06:00 in winter and GMT-05:00 in summer - that is the shift to apply to the time in the report to get local time at the airport.
The closest airports in the database, measured in a straight line from the reference point, are Iowa County Airport (Mineral Point) (KMRJ, 36 km), Boscobel Airport (KOVS, 40 km), Baraboo Wisconsin Dells Regional Airport (KDLL, 48 km). When no report is available for KLNR, they usually give the best approximation of conditions in the area.
