Supporting files for "Climate change may have limited effect on global risk of potato late blight"

Supporting files for "Climate change may have limited effect on global risk of potato late blight" (Sparks et al. 2014). Code is freely available on GitHub, http://adamhsparks.github.io/Global-Late-Blight-Modelling/. <strong>A2 Files</strong> The A2 climate files files are <em>ensemble models</em> (averages) of the following three models: BCCR BCM2.0 (Bjerknes Centre for Climate Research Bergen Climate Model Version 2.0 Commonwealth Scientific and Industrial Research Organization GCM mark 3), CSIRO mk3.0 (Commonwealth Scientific and Industrial Research Organization GCM mark 3) and INMCM3.0 (Institute for Numerical Mathematics Version 3.0 Model). The original A2 emission scenario files were obtained from the Program for Climate Model Diagnosis and Intercomparison (PCMDI) and the WCRP Working Group on Coupled Modelling (WGCM) and downscaled using the delta method to 10 arcminute resolution. Data include maximum temperature, minimum temperature, mean temperature, relative humidity and precipitation. Three time-slices are represented: 2000-2019, 2040-2059 and 2080-2099. <strong> Daily and Monthly Files</strong> These tables contain blight units as calculated by the SimCast model, using HUSWO (Hourly US Weather Observations; NOAA) for resistant and susceptible potato cultivars. These files are used for the creation of the SimCastMeta GAM (Sparks et al. 2011). Daily files are the original blight unit output from the SimCast model (Grünwald et al. 2002) and corresponding temperature and relative humidity values. Monthly files are monthly averages of blight units and corresponding temperature and relative humidity values. <strong>SimCastMeta Look Up Files</strong> These tables contain the blight unit output of the SimCastMeta model along with corresponding temperature and relative humidity values which generate the blight units. Can be used in other applications as a look-up table rather than recreating the whole model in R.

本数据集为论文《气候变化对全球马铃薯晚疫病风险的影响或有限》（Sparks等，2014）的配套支持文件。代码已在GitHub平台开源：http://adamhsparks.github.io/Global-Late-Blight-Modelling/。

### A2 数据集文件
A2气候数据集文件为以下三种模式的**集合模式（ensemble models）**平均结果：BCCR BCM2.0（挪威卑尔根气候研究中心卑尔根气候模式2.0版）、CSIRO mk3.0（英联邦科学与工业研究组织GCM第3代模式）以及INMCM3.0（数值数学研究所模式3.0版）。原始A2排放情景文件来源于气候模式诊断与对比计划（Program for Climate Model Diagnosis and Intercomparison, PCMDI）与世界气候研究计划（WCRP）耦合模式工作组（Working Group on Coupled Modelling, WGCM），并通过delta降尺度法处理至10角分的空间分辨率。数据集涵盖最高气温、最低气温、平均气温、相对湿度与降水数据，包含三个时间切片：2000-2019年、2040-2059年及2080-2099年。

### 日度与月度数据集文件
本部分表格包含由SimCast模型计算得到的疫病单位，其输入数据为美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）的逐小时美国气象观测数据（Hourly US Weather Observations, HUSWO），适用于抗病与感病马铃薯品种。本数据集用于构建SimCastMeta广义可加模型（Generalized Additive Model, GAM，Sparks等，2011）。其中，日度数据集为SimCast模型原始输出的疫病单位数据及对应气温、相对湿度值（Grünwald等，2002）；月度数据集则为疫病单位、对应气温与相对湿度的月度平均值。

### SimCastMeta查找表文件
本部分表格包含SimCastMeta模型输出的疫病单位数据，以及生成该疫病单位所需的对应气温与相对湿度值。该查找表可直接应用于其他场景，无需在R语言环境中重新构建完整模型。
