AMSR-E/AMSR2 Unified L3 Global 5-Day 25 km EASE-Grid Snow Water Equivalent, Version 1

This AMSR-E/AMSR2 Unified Level-3 (L3) data set provides 5-day maximum estimates of Snow Water Equivalent (SWE). SWE was derived from brightness temperature measurements acquired by the Advanced Microwave Scanning Radiometer 2 (AMSR2) instrument on board the JAXA GCOM-W1 satellite.

The SWE data is rendered to an azimuthal 25 km Equal-Area Scalable Earth Grid (EASE-Grid) for both the Northern and Southern Hemisphere.

Note: This data set uses JAXA AMSR2 Level-1R (L1R) input brightness temperatures that are calibrated, or unified, across the JAXA AMSR-E and JAXA AMSR2 L1R products.

本AMSR-E/AMSR2统一三级（Level-3，L3）数据集提供雪水当量（Snow Water Equivalent, SWE）的5日最大值估算结果。雪水当量的计算基于搭载于日本宇宙航空研究开发机构（JAXA）GCOM-W1卫星的先进微波扫描辐射计2（Advanced Microwave Scanning Radiometer 2, AMSR2）所获取的亮温测量数据。
该雪水当量数据被投影至分辨率为25公里的方位等积可缩放地球网格（Equal-Area Scalable Earth Grid, EASE-Grid），覆盖北半球与南半球。
注：本数据集所使用的JAXA AMSR2一级1R（Level-1R, L1R）输入亮温数据，已完成跨JAXA AMSR-E与JAXA AMSR2 L1R产品的定标与统一处理。
