中国无霜期及其时空变化公里网格数据集(1951-2012)
收藏资源简介:
在中国824个气象台站1951-2012年最低气温观测记录基础上,采用7种不同的计算模型,分别计算出中国无霜期时空变化7种不同的数据产品,内容包括:(1)多年平均无霜期空间分布数据、(2)无霜期标准差空间分布数据,(3)初霜日标准差空间分布数据(4)终霜日标准差空间分布数据、(5)初霜日线性倾向率空间分布数据(6)终霜日线性倾向率空间分布数据(7)无霜期线性倾向率空间分布数据。数据以Tiff格式存储,压缩后数据量为170MB。
Based on the minimum temperature observation records from 824 meteorological stations in China during 1951–2012, seven different calculation models were used to generate seven distinct data products on the spatiotemporal variations of the frost-free period in China, including: (1) Spatial distribution data of multi-year average frost-free period; (2) Spatial distribution data of the standard deviation of the frost-free period; (3) Spatial distribution data of the standard deviation of the first frost date; (4) Spatial distribution data of the standard deviation of the last frost date; (5) Spatial distribution data of the linear trend rate of the first frost date; (6) Spatial distribution data of the linear trend rate of the last frost date; (7) Spatial distribution data of the linear trend rate of the frost-free period. All data are stored in TIFF format, with a compressed size of 170 MB.
