Weather Information-Master - Infrared satellite imagery and aviation weather forecast (2007-10-04)

Sep 10, 2026

Uploaded by Ivy

Infrared satellite imagery over Pagosa Springs, Colorado (2230-2330 MDT) is used to assess temperature enhancement and cloud-top temperatures across an accident area. Regional upper-air data, Doppler weather radar sites, and a radar summary chart support analysis, followed by an aviation area forecast for Colorado. Aviation weather conditions are presented by state with outlook periods, cloud coverage, tops, visibility, precipitation type, and turbulence hazards. Additional AIRMET statements define turbulence and IFR/mountain obscuration risks until 0900 MDT.

FAQs

What does the infrared satellite imagery section provide for the accident area?

It lists temperature enhancement thresholds and indicates cloud-top temperatures (approximately -12°C in the accident area). It also categorizes colder cloud regions by color ranges (green through blue/white).

Which weather data sources are referenced to support the forecast?

The document references upper-air data from the NAM model, Doppler weather radar data at 2315 MDT, radar site status/angles, and a radar summary chart. It also includes an aviation area forecast for Colorado.

What hazards are highlighted in the AIRMET alerts?

AIRMET Tango defines areas with moderate turbulence within specified flight levels and time windows. AIRMET Sierra addresses IFR conditions and mountain obscuration, noting where obscuration is expected due to clouds, precipitation, or fog/brief visibility impacts.
