PRISM data converted into FIPS, ZIP Code, and census tract summaries in the USA

PRISM data converted into FIPS, ZIP Code, and census tract summaries in the USA Introduction: Parameter-elevation Regressions on Independent Slopes Model (PRISM) by PRISM Climate group Oregon State temperature, precipitation 4km daily weather variable grids that I have converted to daily county FIPS, ZIP Code, and census tract summaries for use in several papers. Available for download (see Data below) in RDS (compact) format. CSV available on request. In Python it is easy to load RDS files and much more compact files than CSVs too. Note that ZIP Code throughout is actually ZIP Code Tabulation Area (ZCTA), which was developed to overcome the difficulties in precisely defining the land area covered by each ZIP Code. Defining the extent of an area is necessary in order to tabulate census data for that area.

美国PRISM数据集（转换为FIPS代码、邮政编码及人口普查片区汇总单元）：本数据集基于俄勒冈州立大学PRISM气候小组开发的参数-高程独立斜率回归模型（Parameter-elevation Regressions on Independent Slopes Model, PRISM）生成的4千米分辨率逐日气温、降水气象变量网格数据，经处理转换为以美国县级FIPS代码（Federal Information Processing Standards，联邦信息处理标准）、邮政编码（ZIP Code）区域及人口普查片区（census tract）为统计单元的逐日汇总数据，可用于多项学术研究。该数据集可下载获取（详见下文"数据"部分），格式为RDS（紧凑存储格式）；CSV格式数据可按需申请。在Python环境中可轻松加载RDS格式文件，且该格式文件远较CSV文件更为紧凑。请注意，本文中提及的"邮政编码（ZIP Code）"实际为邮政编码统计区域（ZIP Code Tabulation Area, ZCTA）。该区域类型的开发旨在解决精准界定单个邮政编码所覆盖陆地区域的难题，而准确定义区域范围是对该区域的人口普查数据进行汇总统计的必要前提。
