CAR ARCTAS BRDF Measurements V2 (CAR_ARCTAS_BRDF) at GES DISC

ARCTAS focuses on advancing understanding of the factors driving current changes in the Arctic region including transport of mid-latitude pollution, boreal forest fires, aerosol radiative forcing, and chemical processes. ARCTAS aimed to use detailed observations from aircraft to provide the validation, retrieval constraints, correlative data, and process information needed to better achieve the potential of satellites for Arctic research. The plan is for the combination of satellite and aircraft data to provide together powerful information for constraining and evaluating models of Arctic atmospheric composition and climate, and thus improve model projections of future change.

The first phase of ARCTAS was based in Fairbanks and Barrow, Alaska with some flights to Thule, Greenland in April and focused on thick aerosol layers known as “arctic haze.” The second phase followed in July based from Cold Lake, Alberta and the Northwest Territories focusing on the emissions from large boreal forest fires in northwest Canada.

This data set consists of observations made with the CAR instrument and includes values for bidirectional reflectance factor at varying spectral bands.

ARCTAS项目致力于深化对驱动北极地区当前变化的因素的理解，包括中纬度污染的传输、北方森林火灾、气溶胶辐射强迫和化学过程。该项目旨在利用飞机上的详细观测数据，提供验证、检索约束、相关数据和过程信息，以更好地发挥卫星在北极研究中的潜力。计划结合卫星和飞机数据，共同提供强大的信息，以约束和评估北极大气组成和气候模型，从而提高对未来变化的预测。ARCTAS项目的第一阶段以阿拉斯加的费尔班克斯和巴罗为基地，并在四月进行了一些飞往格陵兰岛图勒的航班，专注于被称为“北极烟雾”的浓密气溶胶层。第二阶段于七月从阿尔伯塔省的冷湖和西北地区启动，专注于加拿大西北部大型北方森林火灾的排放。本数据集包含使用CAR仪器进行的观测，包括不同光谱波段的反射率因子值。
