For each of the 17 time periods for each of the 8 meteorological variables have calculated the: (a) average; (b) maximum; (c) minimum; (d) average plus standard deviation (stddev); (e) average minus stddev; (f) stddev; and (g) trend\r\n\r\n\r\n\r\nRisbey_Remote_Rainfall_Drivers_Corr_Coeffs_BA_NSB_GLO.csv\r\n\r\nCorrelation coefficients (-1 to 1) between rainfall and 4 remote rainfall drivers between 1957-2006 for the four seasons.

(2009) paper, the rainfall was from 0.05 degree gridded data described in Jeffrey et al. (2001 - known as the SILO datasets); sea surface temperature was from the Hadley Centre Sea Ice and Sea Surface Temperature dataset (HadISST) on a 1 degree grid.

## **摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）基于多个源数据集衍生而来。源数据集在本元数据声明的Lineage字段中标识，生成该衍生数据集所采用的流程在本元数据声明的History字段中描述。

本数据集包含4个CSV文件：

BAWAP_P_annual_BA_SYB_GLO.csv

描述：1900-2012年BAWAP年均降雨量时间序列

源数据：\wronProjectBABA_N_SydneyWorkingli036_Lingtao_LIGridsBILO_Rain_Ann路径下的年度BILO降雨量数据

P_PET_monthly_BA_SYB_GLO.csv

描述：1981年1月-2012年12月各月份的BAWAP长期平均降雨量与Penman潜在蒸散量（PET）

Climatology_Trend_BA_SYB_GLO.csv

描述：针对1981-2012年（含）期间的17个时间周期（即年度、4个季节及12个月份），计算了以下8个气象变量的数值：（i）BAWAP_P；（ii）Penman ETp；（iii）平均气温（Tavg）；（iv）最高气温（Tmax）；（v）最低气温（Tmin）；（vi）水汽压亏缺（VPD）；（vii）净辐射（Rn）；（viii）风速。对于每个时间周期的每个变量，均计算了以下统计量：（a）平均值；（b）最大值；（c）最小值；（d）平均值加标准差（stddev）；（e）平均值减标准差；（f）标准差；（g）趋势

Risbey_Remote_Rainfall_Drivers_Corr_Coeffs_BA_NSB_GLO.csv

描述：1957-2006年期间降雨量与4种远程降雨驱动因子之间的相关系数（范围-1至1），按四个季节统计。数据与方法详见Risbey等人（2009）的研究。本分析所用所有数据均直接来自霍巴特CMAR的James Risbey。如Risbey等人（2009）论文所述，降雨量数据来自Jeffrey等人（2001）描述的0.05度网格化数据（即SILO数据集）；海表温度数据来自哈德利中心海冰与海表温度数据集（HadISST），分辨率为1度网格。其中，BLK代表阻塞（Blocking），DMI代表偶极子模式指数（Dipole Mode Index），SAM代表南方环状模（Southern Annular Mode），SOI代表南方涛动指数（Southern Oscillation Index）；DJF代表12月-次年2月，MAM代表3-5月，JJA代表6-8月，SON代表9-11月。本分析是Risbey等人（2009）研究中图15的摘要

## **数据集历史**

本数据集由多种BILO源数据创建，包括月度BILO降雨量、最高气温（Tmax）、最低气温（Tmin）、水汽压亏缺（VPD）等，以及其他源数据如月度Penman潜在蒸散量（PET，由Randall Donohue计算）、来自James Risbey的相关系数数据
