GHRSST Level 2P 1 m Depth Global Sea Surface Temperature from VIIRS on Suomi NPP (GDS2) V2

A global Group for High Resolution Sea Surface Temperature (GHRSST) Level 2P dataset based on retrievals from the Visible Infrared Imaging Radiometer Suite (VIIRS). This sensor resides on the Suomi National Polar-orbiting Operational Environmental Satellite System (NPOESS) Preparatory Project (NPP) satellite launched on 28 October 2011.
The VIIRS instrument is a a 22-band, multi-spectral scanning radiometer with a 3040-km swath width that builds on the heritage of the MODIS , AVHRR and SeaWIFS sensors for sea surface temperature (SST) and ocean color. For the infrared bands for SST the effective pixel size is 740 meters at nadir and the pixel size variation across the swath is constrained to no more than 1600 meters at the edge of the swath. However, the processing of this dataset aggregates two pixels into one so the resolution is 1500 meters at nadir. This dataset adheres to the GHRSST Data Processing Specification (GDS) version 2 format specifications.

本数据集为全球高分辨率海表温度（GHRSST）二级P级数据集，基于可见光-红外成像辐射计套装（VIIRS）的探测结果。该传感器搭载于美国国家极地轨道业务环境卫星系统（NPOESS）预备项目（NPP）卫星之上，该卫星于2011年10月28日发射升空。VIIRS仪器是一款具有22个波段的多光谱扫描辐射计，其扫描宽度达到3040公里，继承了中分辨率成像光谱仪（MODIS）、先进宽视场红外辐射计（AVHRR）和海洋水色成像仪（SeaWIFS）在海表温度（SST）和海洋颜色探测方面的优良传统。对于SST的红外波段，有效像素大小为740米，且在扫描宽度边缘的像素大小变化被限制在不超过1600米。然而，该数据集的处理过程将两个像素合并为一个，因此其分辨率在视场中心为1500米。本数据集遵循GHRSST数据处理规范（GDS）第二版格式规范。
