Australian 5km evaporation, radiation and related products - FAO56 crop reference

Data contained in this directory span the period 1 JAN 1981 to 31 DEC 2010 and comprise estimates of potential evaporation formulated using a variety of methods as well as intermediary datasets used to create the potential evaporation data. The main intermediary datasets relate to surface radiation but also include windspeed, vapour pressure deficit and air temperature. In addition, two 'reference datasets' are included: FAO56 crop reference evapotranspiration (Allen et al., 1998) and 'PenPan' evaporation (Rotstayn et al. 2006), which is synthetic US Class A pan evaporation. The source data (maximum and minimum air temperature, vapour pressure) are not available through this website (see Jones et al. (2009) for access).\n

本目录收录的数据时间跨度为1981年1月1日至2010年12月31日，包含采用多种方法估算得到的潜在蒸发量（potential evaporation），以及用于生成该潜在蒸发量数据集的中间数据集（intermediary datasets）。核心中间数据集与地表辐射相关，同时涵盖风速、水汽压差（vapour pressure deficit）与气温（air temperature）数据。此外，本数据集还包含两份参考数据集：其一为FAO56作物参考蒸散量（FAO56 crop reference evapotranspiration，Allen等，1998），其二为PenPan蒸发量（Rotstayn等，2006），该数据集为合成的美国A级蒸发皿蒸发量（US Class A pan evaporation）。本数据集的源数据（最高气温、最低气温与水汽压）无法通过本网站获取，获取方式详见Jones等（2009）的相关研究。
