FIREX-AQ Satellite And Related Ancillary Data

FIREXAQ_Satellite_Data are supplementary satellite and related ancillary data collected during FIREX-AQ. This product includes data from the VIIRS, GOES-16, and GOES-17 satellites. Data collection for this product is complete.

Completed during summer 2019, FIREX-AQ utilized a combination of instrumented airplanes, satellites, and ground-based instrumentation. Detailed fire plume sampling was carried out by the NASA DC-8 aircraft, which had a comprehensive instrument payload capable of measuring over 200 trace gas species, as well as aerosol microphysical, optical, and chemical properties. The DC-8 aircraft completed 23 science flights, including 15 flights from Boise, Idaho and 8 flights from Salina, Kansas. NASA’s ER-2 completed 11 flights, partially in support of the FIREX-AQ effort. The ER-2 payload was made up of 8 satellite analog instruments and provided critical fire information, including fire temperature, fire plume heights, and vegetation/soil albedo information. NOAA provided the NOAA-CHEM Twin Otter and the NOAA-MET Twin Otter aircraft to measure chemical processing in the lofted plumes of Western wildfires. The NOAA-CHEM Twin Otter focused on nighttime plume chemistry, from which data is archived at the NASA Atmospheric Science Data Center (ASDC). The NOAA-MET Twin Otter collected measurements of air movements at fire boundaries with the goal of understanding the local weather impacts of fires and the movement patterns of fires. NOAA-MET Twin Otter data will be archived at the ASDC in the future. Additionally, a ground-based station in McCall, Idaho and several mobile laboratories provided in-situ measurements of aerosol microphysical and optical properties, aerosol chemical compositions, and trace gas species.

The Fire Influence on Regional to Global Environments and Air Quality (FIREX-AQ) campaign was a NOAA/NASA interagency intensive study of North American fires to gain an understanding on the integrated impact of the fire emissions on the tropospheric chemistry and composition and to assess the satellite’s capability for detecting fires and estimating fire emissions. The overarching goal of FIREX-AQ was to provide measurements of trace gas and aerosol emissions for wildfires and prescribed fires in great detail, relate them to fuel and fire conditions at the point of emission, characterize the conditions relating to plume rise, and follow plumes downwind to understand chemical transformation and air quality impacts.

FIREXAQ_Satellite_Data系在FIREX-AQ任务期间收集的补充卫星及相关辅助数据。该产品包含了VIIRS、GOES-16和GOES-17卫星的数据。该产品的数据收集工作已圆满完成。

FIREX-AQ任务于2019年夏季进行，结合了装备精良的飞机、卫星和地面仪器。美国宇航局NASA的DC-8飞机进行了详细的火羽采样，该飞机配备了一套全面的仪器载荷，能够测量超过200种痕量气体物种，以及气溶胶的微物理、光学和化学性质。DC-8飞机共完成了23次科学飞行，其中15次从爱达荷州的博伊西起飞，8次从堪萨斯州的萨利纳起飞。NASA的ER-2飞机完成了11次飞行，部分是为了支持FIREX-AQ任务。ER-2的载荷由8台卫星模拟仪器组成，提供了关键性的火灾信息，包括火灾温度、火羽高度以及植被/土壤反照率信息。美国国家海洋和大气管理局NOAA提供了NOAA-CHEM双引擎飞机和NOAA-MET双引擎飞机，用于测量西部野火上升羽中的化学过程。NOAA-CHEM双引擎飞机专注于夜间火羽化学，相关数据已存档于美国宇航局大气科学数据中心（ASDC）。NOAA-MET双引擎飞机收集了火灾边界处的空气运动测量数据，旨在理解火灾对当地天气的影响以及火灾的移动模式。NOAA-MET双引擎飞机的数据未来也将存档于ASDC。此外，位于爱达荷州麦克劳的地面站和数个移动实验室提供了现场测量的气溶胶的微物理和光学性质、气溶胶的化学组成和痕量气体物种。

火灾对区域至全球环境和空气质量的影响（FIREX-AQ）是一项由NOAA/NASA联合机构进行的密集研究，旨在深入了解北美火灾对对流层化学和组成的综合影响，并评估卫星在检测火灾和估算火灾排放方面的能力。FIREX-AQ的总目标是提供对野火和规定火灾中痕量气体和气溶胶排放的详细测量，将它们与排放点的燃料和火灾条件联系起来，描述与羽流上升相关的条件，并追踪羽流向下游以理解化学转化和空气质量影响。数据收集工作已全部完成。
