Snow Phenology S2 2016-present (raster 100 m), Europe, annually

The Sentinel-2 Snow Phenology (SP S2) product is generated once a year at European scale, based on Fractional Snow Cover (FSC) products calculated from Sentinel-2 optical data. This product describes the snow season in terms of temporality as it provides, within an hydrological year and for each pixel, the number of days with snow cover, as well as the first and the last day of the longest observed snow period. It has a spatial resolution of 100 m x 100 m.
Each product is composed of separate files corresponding to the different layers of the product, and another metadata file."
The product is also available in another projection as tiles aligned with Sentinel-2 (UTM/WGS84) at 20 m x 20 m.
SP S2 is one of the products of the pan-European High-Resolution Water Snow & Ice portfolio (HR-WSI), which are provided at high spatial resolution from the Sentinel-2 and Sentinel-1 constellations data from September 1, 2016 onwards.

哨兵二号积雪物候（Sentinel-2 Snow Phenology, SP S2）产品每年生成一次，覆盖欧洲全域，其数据基础为基于哨兵二号（Sentinel-2）光学遥感数据计算得到的积雪覆盖比例（Fractional Snow Cover, FSC）产品。该产品从时序维度刻画积雪季节特征：在一个水文年内，针对每个像元，提供积雪覆盖总天数，以及观测到的最长积雪时段的起始与结束日期。其空间分辨率为100米×100米。
每份产品由对应产品不同图层的独立文件，以及一份元数据文件共同组成。
该产品还提供另一种投影版本，即采用UTM/WGS84投影、与哨兵二号（Sentinel-2）匹配的瓦片格式，空间分辨率为20米×20米。
SP S2是泛欧洲高分辨率水雪冰数据集组合（pan-European High-Resolution Water Snow & Ice portfolio, HR-WSI）的产品之一，该组合数据集自2016年9月1日起，依托哨兵二号（Sentinel-2）与哨兵一号（Sentinel-1）卫星星座的遥感数据生成，全系产品均具备高空间分辨率特性。
