Introduction of a additive description for old and new weather conditions
Signed-off-by: Markus Waldmann [email protected] & Markus Pauly [email protected]
Description
Introduction of the use of continuous values instead of enums for several weather-values for example:
- Clouds: OSC & OSI provide 5 states. However, the cloud cover is officially divided into eighth values between 0 and 1: like in the Glossar of the German weather department DWD (dwd.de - https://www.dwd.de/DE/service/lexikon/Functions/glossar.html?lv2=100932&lv3=101016). This values should be adapted to each other.
- Ambient Illumination: Describes the Illumination in the environment in LUX, consists of 11 values. Should be described by continuous double values
- Precipitation: Contains 9 possible values Continuous values, should be described by double values - instead of categories according to the context of ISO 2315
- Fog Density: 10 enum values describe the visibility/density in "m" (meter), should be described by double values
@kmeids Before bringing the PR to ReadyToMerge, we would need some feedback from the SensorModeling group.
@thempen I only see an open Issue, is there a PR?
FYI: In the SM group we already had several discussions on this topic and alignments with OSC as well. We went through several suggestions and initially agreed on one that @jruebsam is trying to draft the first message structure. We need to align during our next SM or Harmonization meeting (depending on your and @jruebsam's availability).
Within the new OpenSCENARIO project this is for discussion:
Definition of cloud states using the fractional cloud cover in oktas.
International commision on illumination (CIE):
"Quotient of the sum of the solid angles subtended by clouds and the solid angle 2π sr of the whole sky.
Note 1 to entry: Observation of total cloud amount is usually recorded in tenths or oktas, where one okta indicates an extent of cloud cover equal to one eighth of the sky.
Note 2 to entry: The total cloud amount has unit one. Note 3 to entry: This entry was numbered 845-09-92 in IEC 60050-845:1987.
Note 4 to entry: This entry was numbered 17-1321 in CIE S 017:2011."
