GOES IMPACTS

The GOES IMPACTS dataset consists of single reflective band radiance products from the Advanced Baseline Imager (ABI) onboard the GOES-16 geostationary satellite. These data were collected in support of the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) field campaign. IMPACTS was a three-year sequence of winter season deployments conducted to study snowstorms over the U.S Atlantic Coast (2020-2023). The campaign aimed to (1) Provide observations critical to understanding the mechanisms of snowband formation, organization, and evolution; (2) Examine how the microphysical characteristics and likely growth mechanisms of snow particles vary across snowbands; and (3) Improve snowfall remote sensing interpretation and modeling to significantly advance prediction capabilities. The GOES IMPACTS dataset files are available in netCDF-4 format from January 1 through February 29, 2020. This dataset contains data from the GOES-16 CONUS and Mesoscale sectors, although IMPACTS uses a subset of the GOES-16 CONUS domain. The complete collection of GOES data is available from the NOAA Comprehensive Large Array-Data Stewardship System (CLASS). It should be noted that this dataset will be updated in subsequent years of the IMPACTS campaign.

GOES IMPACTS 数据集由GOES-16地球同步卫星上搭载的高级基线成像仪（ABI）产生的单一反射波段辐射度产品组成。这些数据收集旨在支持对大西洋沿岸威胁性暴风雪微物理和降水的调查（IMPACTS）现场活动。IMPACTS是一项为期三年的冬季部署序列（2020-2023），旨在研究美国大西洋沿岸的暴风雪。该活动旨在（1）提供对雪带形成、组织和演化的机制至关重要的观测；（2）考察雪粒的微物理特征及其可能的增长机制在雪带间的变化；（3）提升降雪的遥感解释和建模能力，以显著推进预测能力。GOES IMPACTS 数据集文件以netCDF-4格式提供，时间范围为2020年1月1日至2020年2月29日。该数据集包含GOES-16 CONUS和区域数据，尽管IMPACTS仅使用了GOES-16 CONUS域的一个子集。完整的GOES数据集可通过美国国家海洋和大气管理局（NOAA）的全面大型阵列数据保管系统（CLASS）获取。值得注意的是，该数据集将在IMPACTS活动的后续年份中得到更新。
