NOAA's climate data record program

Climate Data Record (CDR) is a time series of measurements of sufficient length, consistency and continuity to determine climate variability and change. The fundamental CDRs include sensor data, such as calibrated radiances and brightness temperatures, that scientists have improved and quality-controlled along with the data used to calibrate them. The thematic CDRs include geophysical variables derived from the fundamental CDRs, such as sea surface temperature and sea ice concentration, and they are specific to various disciplines.

气候数据记录（CDR）系指一系列测量值的时间序列，其长度、一致性和连续性足以确定气候的变异与变化。基本气候数据记录包括经过科学家改进和质控的传感器数据，如校准辐射亮度和亮度温度，以及用于校准这些数据的原始数据。主题气候数据记录则包括由基本气候数据记录派生出的地球物理变量，例如海表温度和海冰浓度，它们针对不同学科具有特定的针对性。
