A scan (or sweep) is made by the radar at a certain elevation angle. The
resulting parameter data (param
) are organized along radar range (bins) and
azimuth (rays). A scan (scan
) object is a list containing:
radar
: Radar identifier.
datetime
: Nominal time of the volume to which the scan belongs in UTC.
params
: List of scan parameters (param
).
attributes
: List of the scan's what
, where
and how
attributes.
geo
: List of the scan's geographic properties:
lat
: Latitude of the radar in decimal degrees.
lon
: Longitude of the radar in decimal degrees.
height
: Height of the radar antenna in meters above sea level.
elange
: Elevation angle of the radar beam for that scan in degrees.
rscale
: Range bin size for that scan in m (e.g. 500 m * 480 bins equals
240 km range).
ascale
: Azimuth bin size for that scan in degrees (e.g. 1 degree * 360
rays equals full circle).
rstart
: The range where the first range gate starts in meters (note ODIM stores it as kilometers)
astart
: The start of the first ray.
For summary.scan()
: prints a summary of the scan
object
For is.scan()
: TRUE
for an object of class scan
, otherwise
FALSE
.
For dim.scan()
: number of parameters (param
), bins and rays in a
scan (scan
).
