OMPS-NPP L2 LP University of Saskatchewan

This dataset provides aerosol and ozone profile retrievals performed at the University of Saskatchewan for the central slit of the Ozone Mapping and Profiler Suite Limb Profiler (OMPS-LP) instrument on the Suomi-NPP satellite. The two-dimensional retrieval algorithm accounts for variation in the along orbital track dimension, retrieving an entire orbit simultaneously instead of treating each image independently. Each granule contains data from the daylight portion of each orbit measured for a full month. Spatial coverage is global (-82 to +82 degrees latitude), and there are about 14.5 orbits per day, each has typically 160 profiles with an along orbital track sampling of 125 km. The files are written using NetCDF4.本数据集提供由萨斯喀彻温大学（University of Saskatchewan）针对Suomi-NPP卫星上的臭氧测绘与廓线探测套件临边探测仪（Ozone Mapping and Profiler Suite Limb Profiler，OMPS-LP）中心狭缝开展的气溶胶与臭氧廓线反演数据。该二维反演算法考虑了沿轨方向的维度变化，支持同时对整条轨道进行反演，而非独立处理单幅影像。每个数据粒包含一整月内各轨道的昼间观测数据。空间覆盖范围为全球，纬度跨度为-82°至+82°；日均轨道数约14.5条，单条轨道通常包含160条廓线，沿轨采样间距为125千米。数据文件采用NetCDF4格式存储。
