advr is a package for the scientific research program of CO~2~ advection.
The CO~2~ advection measurement consists with integrated observations of air temperature, humidity, 2D wind velocity, CO~2~ mixing ratio profile, and chamber flux. The measurement procedure is controlled by a data logger and a microcontroller.
advr has the following features.
In the future more features will come.
# load the advr package library(advr) # download the datalogger program (.CR1) get_logger() # download the microcontroller program (.ino) get_arduino() # download a demo data file get_data() # read the raw data file and pre-process the data adv_data <- read_adv("demo/data_sample.csv", "demo/data_header.csv") # configure the file names for the sensors colname_ws <- paste('mean_wind_speed', 1:4, sep = '') colname_wd <- paste('resultant_mean_wind_direction', 1:4, sep = '') colname_t <- c(paste('hcT_Avg(', 1:8, ')', sep = ''), paste('chamberT_Avg(', 1:3, ')', sep = '')) # visualize the raw data by day plot_adv(aa = adv_data) # visualize the entire raw data file plot_adv(aa = adv_data, sub_by = NA)
