VEMAP 2: Monthly Ecosystem Model Responses to U.S. Climate Change, 1994-2100

Phase 2 developed historical (1895-1993) gridded data sets of climate (temperature, precipitation, solar radiation, humidity, and wind speed) and projected (1994-2100) gridded annual and monthly climate data sets using output from two climate system models [CCCma (Canadian Centre for Climate Modeling and Analysis) and Hadley Centre models]. Two Phase 2 model experiments were run. First, a set of selected biogeochemical models and coupled biogeochemical-biogeographical models were run from 1895 to 1993 to compare model responses to the historical time series and current ecosystem biogeochemistry. Second, these same models were run on the projected 1994 to 2100 data to compare their ecological responses to transient scenarios of climate and atmospheric CO2 change. Model runs were performed for daily, monthly, and annual gridded data sets. The output of the monthly model runs in VEMAP grid format are contained in this data set.

第二阶段构建了历史时期（1895-1993年）的气候（温度、降水量、太阳辐射、湿度和风速）网格化数据集，以及基于两种气候系统模型（加拿大气候建模和分析中心[CCCma]和哈德莱中心模型）的预测（1994-2100年）网格化年度和月度气候数据集。进行了两个第二阶段的模型实验。首先，运行了一组精选的生物地球化学模型以及耦合的生物地球化学-生物地理学模型，时间跨度为1895年至1993年，以比较模型对历史时间序列和当前生态系统生物地球化学的响应。其次，将这些相同的模型应用于预测的1994年至2100年的数据，以比较其在气候和大气CO2变化的瞬时情景下的生态响应。对每日、每月和年度的网格化数据集进行了模型运行。本数据集包含了基于VEMAP网格格式的月度模型运行输出。
