中国区域250米EVI侯合成产品（TERRA星）

产品介绍：MODEV1F 中国250M EVI五天合成产品（TERRA星）是由MODEV1D计算得到，计算方法为取月内每五天最大值。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 MODEV1F 250-meter 5-day EVI synthesis product over China (TERRA satellite) is derived from the MODEV1D dataset, using the method of generating 5-day maximum value composites within each calendar month.
The naming convention is as follows: AAABBCD. EEEEEEE. CN.FFF.GG****. For example, the daily temperature synthesis product over China is named as MYDLT1D.20010101.CN.LTD.V1.TIF.
Breakdown of each naming convention field:
- AAA: Satellite (MOD&MYD)
- BB: Parameter (Land Surface Temperature (LT), NDV (ND), EVI (EV), SR (Surface Reflectance))
- C: Spatial Resolution (Q (250m), H (500m), 1 (1000m))
- D: Synthesis Cycle (D (Daily), F (5-day synthesis), T (10-day synthesis), M (Monthly synthesis))
Note: For February or long months, the last synthesis product of the month uses the daily data of all remaining days in that month as input. (For example, the 5-day synthesis product for a common February actually uses data from February 26, 27, and 28 as its input.)
CN: China regional synthesis product
EEEEEEE: YYYYDDD format (e.g., 2010001, where YYYY represents the 4-digit year and DDD represents the 3-digit day of the year)
Note: The corresponding timestamp of each synthesis product is set as the first day of the daily input data used for that synthesis product.
FFF: Parameter. LTD: Daytime Land Surface Temperature; LTN: Nighttime Land Surface Temperature; QCD: Daytime Quality Control File; QCN: Nighttime Quality Control File;
GG: Version number;
****: File type (TIF, JPG, TXT).
