********************************** CONTENTS ***********************************
Data are included in four comma-seperated values spreadsheets. All data were collected at an hourly interval between August 1, 2015 and July 31, 2016.

1. README_otc.txt - This file. Includes a  list of all data files, a description of the variables, and contact information.
2. nfc_detailed_microclimate.csv- This is detailed data of three warmed and three ambient plots located at the northern forest clearing at the University of Michigan Biological Station in Pellston, Michigan, USA. Each pair (1,2,3) included two HOBO dataloggers that recorded temperature at 1 meter height, relative humidity at 1 meter height, temperature at 10cm height, soil temperature at -5cm, and soil moisture at -5cm. Each datalogger was set-up with half of its sensors in a warmed plot and half of its sensors in an ambient plot, such that the same type of measurement (i.e. air temperature at 1 meter) was measured by the same logger in an ambient and warmed plot.
3. soaf_detailed_microclimate.csv- This is detailed data of three warmed and three ambient plots located in the old agriculture field at Kellogg Biological Station in Hickory Corners, Michigan, USA. Each pair (1,2,3) included two HOBO dataloggers that recorded temperature at 1 meter height, relative humidity at 1 meter height, temperature at 10cm height, soil temperature at -5cm, and soil moisture at -5cm (Onset Computer Corporation, Bourne, MA). Each datalogger was set-up with half of its sensors in a warmed plot and half of its sensors in an ambient plot, such that the same type of measurement (i.e. air temperature at 1 meter) was measured by the same logger in an ambient and warmed plot.
4. nfc_pendants.csv- This is temperature data at 1 meter height within nine passive open top chambers at the northern forest clearing at the University of Michigan Biological Station in Pellston, Michigan, USA. These data were used to assess variability within the warming method. 
5. soaf_pendants.csv  This is temperature data at 1 meter height within nine passive open top chambers at the old agriculture field at Kellogg Biological Station in Hickory Corners, Michigan, USA. These data were used to assess variability within the warming method.



********************************* VARIABLES **********************************
Microclimate Units:

Temperature (1 meter, 10 cm, -5cm soil): Measured in degrees Celsius.
Relative Humidity: The amount of water vapor present in air expressed as a percentage (1-100).
Soil Moisture: The amount of water in the soil described as a percentage (0-1).


2-3. Variable names and descriptions in nfc_detailed_microclimate.csv and soaf_detailed_microclimate.csv.

"date_time"     Date and Time of measurement taken in the format month/day/year hour:seconds
		
***Remaining variables formatted based on the pair number, logger type, treatment (warmed/ambient), and microclimate variable. 

  "H"    HOBO H21-002 data logger. Measured hourly air temperature and relative humidity at 1m above the soil surface along with soil moisture at 5 cm below the soil in each warmed/ambient pair. 
  "U"	 HOBO Microstation U12-008 data logger. Measured hourly air temperature at 10 cm above the soil surface and 5 cm below the soil in each warmed/ambient pair.
         
Example: "X1H_ambient_soil_moisture_5cm" is data from Pair 1 using a HOBO H21-002 measuring soil moisture in an ambient plot.



4-5. Variable names and descriptions in nfc_pendants.csv and soaf_pendants.csv.

"date_time"    Date and Time of measurement taken in the format month/day/year hour:seconds

***Remaining variables formatted based on sensor number. All pendant measurements taken as hourly temperature at 1 meter height in warmed plots. 

Example: "X4P_temp_1m" is hourly temperature at 1 meter height from pendant four.
