What parameters are included in the Core Data Layer?

Parameter

Description

Notes

Temperature

The "real" temperature measurement (at 2m).

Feels Like

The temperature equivalent perceived by humans, caused by the combined effects of air temperature, relative humidity, and wind speed (at 2m).

Dew Point

The temperature to which air must be cooled to become saturated with water vapor (at 2m).

Humidity

The concentration of water vapor present in the air.

Wind Speed

The fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in temperature (at 10m).

Wind Direction

The direction from which it originates, measured in degrees clockwise from due north (at 10m).

Wind Gust

The maximum brief increase in the speed of the wind, usually less than 20 seconds (at 10m).

Pressure

Precip Intensity

The amount of precipitation that falls over time, covering the ground in a period of time.

Rain Intensity

The amount of rain that falls over time, covering the ground in a period of time.

Freezing Rain Intensity

The amount of freezing rain that falls over time, covering the ground in a period of time.

Snow Intensity

The amount of snow that falls over time, covering the ground in a period of time.

Sleet Intensity

The amount of sleet that falls over time, covering the ground in a period of time.

Precipitation Type

The various types of precipitation often include the character or phase of the precipitation which is falling to ground level (Schuur classification).

This will have a non-zero value if precipitation probability or intensity > 0

Rain Accumulation

The accumulated amount of liquid rain that has or will accumulate for the past or future hour of the requested time.

Ice Accumulation

The accumulated amount of ice from freezing rain that has or will accumulate for the past or future hour of the requested time.

Snow Accumulation

The accumulated amount of new snowfall that has or will accumulate for the past or future hour of the requested time.

Visibility

The measure of the distance at which an object or light can be clearly discerned.

Cloud Cover

The fraction of the sky obscured by clouds when observed from a particular location.

Cloud Base

The lowest altitude of the visible portion of a cloud (above ground level).

Cloud Ceiling

The highest altitude of the visible portion of a cloud (above ground level).
