Wind Vector Over Land Surface (Horizontal) Measurement Instruments

Measurements > Atmosphere > Atmospheric Winds > Wind vector over land surface (horizontal)

Measurement Definition: The wind vector represents the motion of the airmass over the ground. It is described by wind speed and the inverse of wind direction. Conventionally measured at 10 m height.Accuracy is the modulus of the vector difference between measured and true vectors. [Unit ofmeasurement - m/s]

Instrument	Status/ Accuracy	Instrument Description	Measurement Technology	Timeline
AGRI	Operational	A multiple channel radiation imager, one of the primary instruments aboard FY-4. Technically featured by a precisely designed two-mirror structure, capable of accurate and flexible sensing in two dimensions, and minute-level fast sector scanning. Frequent Earth imaging over 14 bands with off-axis three reflections of the primary optic system. On-board black body available for IR calibrations at very short time intervals.	n/a
VIIRS	Operational	Global observations of land, ocean, and atmosphere parameters: cloud/weather imagery, sea-surface temperature, ocean colour, land surface vegetation indices.	n/a
