INSTRUCTIONS: Convert the following manually derived SA information into a METAR format.
1. W3 X METAR = _________________________
2. 15 SCT M45 OVC METAR = _________________________
3. CLR METAR = _________________________
4. M35 BKN (TCU is visible) METAR = _________________________
5. 20 SCT (clouds cover less than 2/10 of the sky) METAR = _________________________
1. VV003
METAR reports indicate total obscurations by encoding the vertical visibility into the obscuration in the body of the report. Vertical visibility is encoded as "VV" followed by the height. This would be considered a ceiling.
2. SCT015 OVC045
METAR reports encode the layer coverage before the layer height. A ceiling designator is not entered.
3. SKC
METAR has two options for encoding clear skies. Automated stations use CLR and manual stations use SKC. Since this is from a manual station, clear would be encoded as SKC.
4. BKN035TCU
Any time CB or TCU are present, they will be encoded in the body of a METAR report. They will be attached to the layer with which their base is associated. Since there was only one layer reported, it would be attached to that layer.
5. FEW020
METAR has an additional reportable value used when the sky coverage is equal to or less than 2/8. This coverage is encoded as "FEW."
