Dataset: Vassar Daily Weather Data

Methods

The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures

Current Methods

• Campbell Scientific Weather Station
  Started: 2017-08-16
  

  Daily measurements of weather variables taken at Vassar Farm and Ecological Preserve at Collins Field Station. Note that TIMESTAMP represents the DateTime for the previous 24 hours, e.g., 8/4/2017 0:00 represents the 24-hour period of 8/3/2017.
