中国区域1KM地表温度日合成产品（AQUA星）

产品介绍：MYDLT1D即中国1KM地表温度（Day&Night）每天产品是由MYD11A1经过拼接、切割、投影转换等过程加工而成。每天数据中包括白天地表温度、夜间地表温度、白天地表反射率、夜间地表反射率四类产品；其中数据比例因子为0.02，单位为开尔文。根据使用需求，可通过计算公式：0.02*value-273.15转换为摄氏温度。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: MYDLT1D, namely China 1KM Land Surface Temperature (Day&Night) Daily Product, is processed from MYD11A1 through processes such as mosaicking, clipping, and projection transformation. Each daily dataset includes four types of products: daytime land surface temperature, nighttime land surface temperature, daytime land surface reflectance, and nighttime land surface reflectance; the data scaling factor is 0.02, with the unit being Kelvin. According to usage requirements, it can be converted to Celsius temperature using the formula: 0.02*value - 273.15. The naming convention is as follows: AAABBCD.EEEEEEEEEE.CN.FFF.GG****, for example: the name of China's daily temperature composite is MYDLT1D.20010101.CN.LTD.V1.TIF; AAA: Satellite (MOD & MYD); BB: Parameter (Land Temperature (LT), NDV (ND), EVI (EV), SR (Land Surface Reflectance)); C: Resolution (Q (250m), H (500m), 1 (1000m)); D: Composite period (D (daily), F (5-day composite), T (10-day composite), M (monthly composite)); Note: For February or months with more days, the last composite product of the month uses all remaining daily data of the month as input. (For example, the 5-day composite product for a common February actually uses data from February 26, 27, and 28 as input); CN: China regional composite; EEEEEEE: YYYYDDD (e.g., 2010001); Note: The composite product uses the first day of the input data for each composite product as the corresponding time of the product; FFF: Parameter (LTD: Daytime land surface temperature; LTN: Nighttime land surface temperature; QCD: Daytime quality assessment file; QCN: Nighttime quality assessment file); GG: Version number; ****: File type (TIF, jpg, txt).
