Note for Wind Measurements
Wind and gust speeds reported at Dawson Bay Li Taan Aen Staansyoon indicate speeds that would be felt nearby on the lake only when the wind blows from SE. The anemometer is sheltered from the full force of the wind by trees and a building in other directions. Wind and gust wind speeds are measured 3 m above the ground surface. Environment Canada and Manitoba Department of Agriculture weather stations report faster speeds because they are recorded on higher, 10 m towers.
| Column | Type | Label | Description | Units | Media type | Result Value Type | Statistic Applied |
|---|---|---|---|---|---|---|---|
| Date_and_time | timestamp | Datetime | String corresponding to format 'YYYY-MM-DDThh:mm:ss.sssZ' or other valid ISO8601 string. |
datetime | atmosphere | Actual | None |
| air_pressure | numeric | Barometric Pressure | Measured using a barometer mounted inside the enclosure that houses the air temperature sensor. It is reported in millibars, where 1,000 millibars is the average air pressure at sea level. Changing pressure often indicates a coming change in the weather. Increasing pressure is associated with clearing skies. Decreasing pressure is associated with increasing cloudiness, and possibly an approaching storm. |
millibar | atmosphere | Actual | None |
| air_pressure_result_value_qualifier | text | Air pressure result value qualifier | A result value qualifier is a code field to identify measurements outside of the sensor calibrated detection range. "ADL" is a measurement above the detection limit and "BDL" is below the detection limit. Additionally, field equipment error code "FEF" is given when the sensor or station is faulty and producing problematic data along with probably bad data code "prob_bad" when data is recognised as unusual during quality control that forms part of a feature that is probably inconsistent with real phenomena. |
NA | atmopshere | Actual | None |
| Photosynthetically_Active_Radiation | numeric | PAR | 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, and light scattered by the sky and clouds. It is reported in a unit called a micro-Einstein. |
microEinstein | atmosphere | Actual | None |
| Photosynthetically_Active_Radiation_result_value_qualifier | text | PAR result value qualifier | A result value qualifier is a code field to identify measurements outside of the sensor calibrated detection range.

NA | atmosphere | Actual | None |
| air_temperature | numeric | Temperature | We report temperature in the shade, in Centigrade degrees. It is measured using an electronic thermometer shielded from direct sunlight, mounted inside an enclosure with louvered walls to allow free air flow past the sensor. |

NA | atmosphere | Actual | None |
| relative_humidity | numeric | RH | The amount of water vapour in the air reported as a percentage of the amount that would saturate it at the air temperature. Warmer air can hold more water vapour than cooler air. |

NA | atmosphere | Actual | None |
| Precip | text | Rain | Reported in millimetres accumulated every 15 minutes in a gauge set about 1 m above the ground. Rain falling into a 6-inch diameter funnel drips onto a 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 equals 0.2 mm of rain. |
