中国区域1KM地表温度月合成产品(TERRA星)
收藏资源简介:
产品介绍:中国1KM地表温度月合成产品(TERRA星)是由MODLT1D产品经过合成计算得到,计算方法为取月平均值。命名规范如下:AAABBCD. EEEEEEEEE. CN.FFF.GG****,比如:中国每日温度合成命名为:MYDLT1D.20010101.CN.LTD.V1.TIF;AAA:卫星(MOD&MYD);BB:参量(地表温度(LT)、NDV(ND)、EVI(EV)、SR(地表反射率));C:分辨率(Q(250米)、H(500米)、1(1000米));D:合成周期(D(每日)、F(5天合成),T(10天合成)、M(月合成)) l 注意:遇2月或大月,每月最后一个合成产品利用本月所有剩余天内的每日数据为输入。(比如平二月的5天合成产品实际数据输入为2月26、27、28三天);CN:中国区域合成 EEEEEEE:年年年年天天天(2010001) 注意:合成产品以每个合成产品输入数据的第一天作为产品对应时间;FFF:参量 LTD:白天地表温度 LTN:夜间地表温度 QCD:白天质量评价文件 QCN:夜间质量评价文件;GG:版本号;****:文件类型(TIF、jpg、txt)。
Product Introduction: The China 1KM Land Surface Temperature Monthly Composite Product (TERRA Satellite) is generated by compositing the MODLT1D product, with the calculation method adopting the monthly average value. The naming convention follows the format: AAABBCD. EEEEEEEEE. CN.FFF.GG****. For example, the daily temperature composite product for China is named MYDLT1D.20010101.CN.LTD.V1.TIF. Breakdown of the naming fields: 1. AAA: Satellite ("MOD & MYD") 2. BB: Parameter (Land Surface Temperature (LT), NDV (ND), EVI (EV), SR (Surface Reflectance)) 3. C: Resolution (Q (250 m), H (500 m), 1 (1000 m)) 4. D: Composite Cycle (D (Daily), F (5-day Composite), T (10-day Composite), M (Monthly Composite)) Note: For February or 31-day months, the final composite product of each month uses all valid daily data from the remaining days of the current month as input. For instance, the 5-day composite product for a non-leap February actually uses data from February 26, 27, and 28 as its input. CN: China regional composite product EEEEEEE: Year and Day of Year (7-digit format: YYYYDDD, e.g., 2010001 represents January 1, 2010). Note: The corresponding timestamp of each composite product is defined as the first day of the daily input data utilized for that composite. FFF: Parameter codes: - LTD: "Daytime Land Surface Temperature" - LTN: "Nighttime Land Surface Temperature" - QCD: "Daytime Quality Assessment File" - QCN: "Nighttime Quality Assessment File" GG: Version number ****: File extension (TIF, JPG, TXT)
