MEaSUREs Global Record of Daily Landscape Freeze/Thaw Status, Version 1

The MEaSUREs Global Record of Daily Landscape Freeze/Thaw Status, Version 01 data set is derived from the Defense Meteorological Satellite Program (DMSP) satellite series using the Special Sensor Microwave Imager (SSM/I). The parameters in this data set include AM freeze thaw, PM freeze thaw, combined freeze thaw, transitional freeze thaw, and inverse transitional freeze thaw states of water. The data set presents global coverage from morning, afternoon, and daily combinedoverpasses from 01 January 1988 to 31 December 2007. The data set is available through FTP and contains files in the HDF5, PNG, and GIF formats. These data were generated through a grant from the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program.

MEaSUREs全球每日地表冻融状态记录（版本1）数据集源自国防气象卫星计划（Defense Meteorological Satellite Program, DMSP）系列卫星搭载的专用传感器微波成像仪（Special Sensor Microwave Imager, SSM/I）。该数据集包含的参数涵盖水体的上午冻融状态、下午冻融状态、综合冻融状态、过渡性冻融状态以及反向过渡性冻融状态。本数据集覆盖1988年1月1日至2007年12月31日期间的上午、下午及每日联合过境时段的全球范围数据。该数据集可通过文件传输协议（File Transfer Protocol, FTP）获取，包含HDF5、PNG及GIF格式的数据文件。本数据集由美国国家航空航天局（National Aeronautics and Space Administration, NASA）的“地球系统数据记录研究环境计划（Making Earth System Data Records for Use in Research Environments, MEaSUREs）”项目资助生成。
