Methods

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

Current Methods

  • Ward Pound Ridge Meteorological Data

    This dataset is part of the Ward Pound Ridge Reservation Environmental Monitoring Program. Data is telemetered every minute. Missing telemetered data is filled in after routine site visits with field collected data sets.

  • Datalogger

    Meteorological and solar radiation data are collected using a Campbell Scientific CR1000. Data is sent on a 1 minute schedule and pooled into a 15 minute dataset.

Dataset Fields

Detailed documentation of the fields comprising the dataset, including the type of measurement, units where applicable, and any controlled vocabularies or code lists present in the data
