cmi: Weather data for Champaign Illinois

In BioCro: Simulation of Biomass Crops

Description

Weather data as produced by the weach function. These are for 2004, 2005 and 2006. The original source is daily weather data from the WARM network IL.

Usage

data(cmi06)

Format

A data frame with 8760 (8784 if leap year) observations on the following 8 variables.

year

year

doy

day of the year

hour

hour

SolarR

solar radiation (micro mol/m2/s)

Temp

temperature (Celsius)

RH

relative humidity (0-1)

WS

wind speed (m s-1)

precip

precipitation (mm)

Source

These data are generated using the weach function. The original data is from the Illinois WARM network. http://www.isws.illinois.edu/warm/data/cdfs/cmiday.txt

Datasets weather04, weather05, weather06 were generated with an old version of weach which presumably did not produce the most realistic sub-daily profiles of realtive humidity and wind speed (they were constant through out the day before).
