AVHRR Polar Atmospheric Motion Vectors Climate Data Record Release 1 - CIMSS Algorithm – Metop-A

Tropospheric satellite winds at all heights below the tropopause in the polar regions (latitudes higher than 65º), derived from the infrared channel of the Metop AVHRR instrument.

This is the first release of polar atmospheric wind vectors that have been reprocessed. They are archived in the EUMETSAT Data Centre. The data record was generated with an adapted version of the Cooperative Institute for Meteorological Satellite Studies (CIMSS) operational algorithm. The data record includes products generated with IR images taken from the AVHRR/3 imager on-board the Metop-A polar satellite. The dataset covers the period March 2007 until December 2014. The coverage boundaries are polar caps polar wards of 65º. The data record is available in two formats, i.e., the EUMETSAT generic EPS format and the BUFR format.

Note that this polar AMV dataset has also been produced using the EUMETSAT operational algorithm (see : Related Product tab).

This is a Thematic Climate Data Record (TCDR).

极地地区（纬度高于65°）对流层顶以下各高度层的对流层卫星风场数据，源自Metop极轨卫星搭载的先进甚高分辨率辐射计（Advanced Very-High-Resolution Radiometer, AVHRR）的红外通道。
本数据集为首批经再处理的极地大气风矢量数据，存档于欧洲气象卫星组织（EUMETSAT）数据中心。该数据记录采用经适配优化的合作气象卫星研究机构（Cooperative Institute for Meteorological Satellite Studies, CIMSS）业务算法生成，涵盖由Metop-A极轨卫星搭载的AVHRR/3成像仪获取的红外影像所生成的各类产品。数据集的时间覆盖周期为2007年3月至2014年12月，空间覆盖范围为65°纬度以北的极地区域。数据记录提供两种存储格式：EUMETSAT通用EPS格式与BUFR格式。
需注意，该极地大气运动矢量（Atmospheric Motion Vectors, AMV）数据集亦可通过欧洲气象卫星组织业务算法生成（详见「相关产品」标签页）。
本数据集属于专题气候数据记录（Thematic Climate Data Record, TCDR）。
