Cumulonimbus (CB) and Tower Cumulus (TCU) missing for cloud covers

[ManojAgrawal]

What should we add?

Hello, I noticed that the current parser does not account for CB or TCU for example with METAR

'KEWR 252303Z 18008KT 10SM -TSRA SCT060CB SCT080 BKN100 OVC200 17/13 A2948 RMK AO2 LTG DSNT SW-N TSB03 OCNL LTGIC VC SW-VC NW CB VC SW-VC NW MOV NE P0000 T01670133 $'

Only scattered clouds at 6000 ft are displayed omitting 'CB'. Is there a plan to include such phenomenons?

thanks

Looks like the parser is looking for them:

MetPy/src/metpy/io/_metar_parser/metar_parser.peg

Lines 18 to 20 in 595e30c

	skyc <- ((sep (cover))*)?
	cover <- (("FEW" / "SCT" / "BKN" / "OVC" / "VV" / "///") ([\d]*)? ("TCU" / "CB" / "//" "/"?)?) / ("CLR" / "SKC" / "NSC" / "NCD") / wx / "//"
	temp_dewp <- ((sep "//"? temp "/" dewp "//"?))?

I'm unclear what you would like to see here? A column in the dataframe noting the presence? A different value for the cloudcover column? Something else?

Hi,

I am using 'io.parse_metar_to_dataframe' parse the metar so we have cloud type and cloud level.

Maybe an extra column for additional type but not sure as it depends on the designer. CB and TCU are rare but should be reported as they indicate dangerous flying conditions.

thanks,
