Google Earth Engine——NOAA/CDR/PATMOSX/V53提供了高质量的气候数据记录（CDR），以及高级甚高分辨率辐射计（AVHRR）的亮度温度和反射率的多种云特性

This dataset provides high quality Climate Data Record (CDR) of multiple cloud properties along with Advanced Very High Resolution Radiometer (AVHRR) brightness temperatures and reflectances. These data have been fitted to a 0.1 x 0.1 equal angle-grid with both ascending and descending assets generated daily from two to ten NOAA and MetOp satellite passes per day.

This dataset includes 48 bands, 11 of which are deemed CDR quality (marked with "CDR variable" in the band list). The cloud products are derived using the ABI (Advanced Baseline Imager) Cloud Height Algorithm (ACHA), and the Daytime Cloud Optical Properties (DCOMP) algorithm. For more detail on the processing see the algorithm theoretical basis documents for the ACHA products, DCOMP products, reflectance and brightness temperature products.

这个数据集提供了高质量的气候数据记录（CDR），以及高级甚高分辨率辐射计（AVHRR）的亮度温度和反射率的多种云特性。这些数据被拟合为0.1 x 0.1的等角网格，每天从两到十次NOAA和MetOp卫星传递中产生上升和下降的资产。

这个数据集包括48个波段，其中11个被认为是CDR质量（在波段列表中标有 "CDR变量"）。云层产品是使用ABI（高级基线成像仪）云高算法（ACHA）和日间云层光学特性（DCOMP）算法得出。关于处理的更多细节，请参见ACHA产品、DCOMP产品、反射率和亮度温度产品的算法理论基础文件。

数据说明：

The NOAA CDR Program’s official distribution point for CDRs is NOAA’s National Climatic Data Center which provides sustained, open access and active data management of the CDR packages and related information in keeping with the United States’ open data policies and practices as described in the President's Memorandum on "Open Data Policy" and pursuant to the Executive Order of May 9, 2013, "Making Open and Machine Readable the New Default for Government Information". In line with these policies, the CDR data sets are nonproprietary, publicly available, and no restrictions are placed upon their use. For more information, see the Fair Use of NOAA's CDR Data Sets, Algorithms and Documentation pdf.
