Arctic Longwave Infrared Satellite Composite Imagery, Version 1.0

This dataset contains longwave infrared (~12.0 microns) Arctic satellite composite imagery. The Arctic composites are made every three hours (synoptic hour) creating a total of eight images per day. Most input satellite observations included in the composite were procured within 15 minutes of the top of the synoptic hour. No image is more than +/- 50 minutes from the top of the synoptic hour. Geostationary and Polar orbiting satellites used to generate the composite can include: Polar-orbiting Operational Environmental Satellites (POES) / National Oceanic and Atmospheric Administration (NOAA), Geostationary Operational Environmental Satellites (GOES) -East and -West, METEOSAT, Meteorological Satellites (MTSAT), FY-2, Kalpana-1, and Terra/Aqua.

本数据集包含长波红外（~12.0微米）频段的北极地区卫星合成影像。该北极合成影像每3小时生成一次（天气时次，synoptic hour），每日总计生成8幅影像。合成影像所用的多数输入卫星观测数据，均采集于天气时次整点前后15分钟内，且所有影像与天气时次整点的时间偏差均不超过±50分钟。用于生成该合成影像的卫星涵盖极轨卫星与地球静止轨道卫星，具体包括：极轨业务环境卫星（Polar-orbiting Operational Environmental Satellites, POES）/美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）卫星、地球静止轨道业务环境卫星（Geostationary Operational Environmental Satellites, GOES）东、西双星、METEOSAT卫星、气象卫星（Meteorological Satellites, MTSAT）、风云二号（FY-2）卫星、卡尔帕纳一号（Kalpana-1）卫星，以及泰拉/阿奎拉（Terra/Aqua）卫星。
