Hurricane and Severe Storm Sentinel (HS3) Scanning High-Resolution Interferometer Sounder (S-HIS) V1

The Hurricane and Severe Storm Sentinel (HS3) Scanning High-Resolution Interferometer Sounder (S-HIS) measures emitted thermal radiances that are used to obtain temperature and water vapor profiles of the Earth's atmosphere in clear-sky conditions. Due to the S-HIS scanning capability, the instrument provides 2 km resolution (at nadir) across a 40 km wide ground swath when flown at an altitude of 20 km onboard the NASA Global Hawk unmanned aircraft. S-HIS data were collected during the 5-week HS3 field campaign study periods in the 2012 to 2014 Atlantic hurricane seasons.

Hurricane and Severe Storm Sentinel（HS3）扫描高分辨率干涉仪探测器（S-HIS）测量地球大气在晴空条件下的辐射热辐射，以此获取大气温度和水汽分布。得益于S-HIS的扫描功能，当搭载于NASA全球鹰无人机的20千米高空进行观测时，该仪器在地面宽度为40千米的范围内提供2千米分辨率的观测数据（近地观测）。S-HIS数据收集于2012年至2014年大西洋飓风季节期间，为期五周的HS3现场研究项目期间。
