_id Original Header Type Cleaned Variable Name CanWIN Common Name Units Data Provider Description Standardized Source Term Standardized Source Term Link Notes media_type result_value_type statistic_applied 1 The exact column name as it appeared in the raw file before any cleaning. The variable’s data type (text, numeric, timestamp, etc.) after cleaning. The standardized, machine‑friendly name produced following data best practices, for e.g., using the CSV Studio’s header cleaning function. Used in the final dataset. A human‑readable name. Helps non‑technical users understand the variable. The physical units associated with the variable (e.g., m, PSU, °C). The description supplied by the original data provider explaining what the variable represents. Standardized scientific term selected from an authoritative vocabulary (e.g., BODC, CF). Ensures consistent meaning across datasets. Link to standardized scientific term and definition. Any notes about how the variable was processed or derived.Extracted from the header or assigned manually. The medium from which the measurement was taken (e.g., water, air, sediment). Extracted from the header or assigned manually. Whether the value is a direct measurement or a calculated value. Any statistical operation applied to the variable (e.g., mean, max, min). “none” if no statistic was applied. 2 Date_Time numeric date_and_time Date and Time UTC Date-Time in ISO format UT_ISO8601 http://vocab.nerc.ac.uk/collection/P01/current/DTUT8601/ actual none 3 Pressure_20812849_mbar numeric air_pressure Air Pressure mbar Pressure (measured variable) exerted by the atmosphere wind_speed_of_gust http://vocab.nerc.ac.uk/collection/P01/current/CAPHZZ01/ Air actual none 4 numeric air_pressure_result_value_qualifier RVQ codes explain missing, unusual, or potentially erroneous data vales.

It is the intensity of the part of sunlight that plants can use to support new growth, and also the wavelengths of light that our eyes are sensitive to. It is measured on a small white disc that records the sum of light falling directly from the sun plus the light scattered by the sky and clouds. It is reported in a unit called a micro-Einstein. SurfVPAR https://vocab.nerc.ac.uk/collection/P01/current/IRRDSV01/ uE means measured in photons, not energy.

Rain falling into a 6-inch diameter funnel drips onto one of a pair of “buckets”, mounted on a teeter-totter. When one bucket is filled, the teeter-totter flips, the first bucket is emptied and rain then drips into the other “bucket” until it is filled, and so on. Each flip is equal to 0.2 mm of rain.

We report the average speed for every 15 minute period, in kilometres per hour. Wind speeds reported at St Laurent Li Taan Aen Staansyoon indicate speeds that would be felt nearby on the lake only when the wind blows from SSW through W to NNW. The anemometer is sheltered from the full force of the wind by trees in other directions. Wind speeds are measured 3 m above the ground surface.
