Notes about METAR AUTO Reports at aerodromes other than NZAA, NZWN, NZCH, NZMF:

  1. At aerodromes where METAR AUTO are issued, no SPECI observations are provided.
  2. METAR AUTO are issued routinely every 30 minutes, on the hour and half-hour, day and night.
  3. Lightning data from an independent lightning detection network will be added to METAR AUTO to provide additional observational data.
  4. METAR AUTO will not include directional visibility variations, “vicinity” (VC) present weather, or cloud type (ie, TCU and CB).
  5. When the weather sensor is temporarily inoperative, two strokes (//) are inserted in the present weather field.
  6. When no cloud is detected below 10,000 feet by the cloud sensor, NCD (no cloud detected) is used instead of SKC (sky clear).
  7. When cloud is detected, three strokes (///) are placed at the end of each cloud layer group, to indicate that the AWS could not identify TCU or CB.

TREND forecast: temporary fluctuations in the visibility and weather (6000 metres and rain) are expected to occur, and will last for a period of less than one hour in each instance. Such fluctuations are expected to occur during the next 2 hours, i.e., between 0000 and 0200 UTC, and to take place sufficiently infrequently for the prevailing conditions to remain those reported in the METAR AUTO

Notes about METAR AUTO Reports - NZAA, NZWN, NZCH only:

  1. No SPECI observations are provided.
  2. METAR AUTO are issued routinely every 30 minutes
  3. Lightning data from an independent lightning detection network will be added to METAR AUTO to provide additional observational data.
  4. Forecasters will add additional information on occasion based on high-resolution satellite and weather radar imagery, and webcams installed at NZAA, NZWN, NZCH. This may include reference to CB or TCU clouds, fog or precipitation at or in the vicinity of the aerodrome.
  5. When the weather sensor is temporarily inoperative, two strokes (//) are inserted in the present weather field.
  6. When cloud is detected, three strokes (///) are placed at the end of each cloud layer group, to indicate that the AWS could not identify TCU or CB. However, CB or TCU will be included if a forecaster is able to observe CB or TCU by reference to the additional observational data referred to in 4. above

Volcanic Ash Graphic (VAG)

VAG example

See larger (100 KB)

Explanation of a VAG

A VAG is presented as a 4-panel map displaying volcanic ash observed from an aircraft, satellite picture or other means, as well as the forecast location of the ash at 6, 12 and 18 hours after the time the ash was observed. The ash is displayed in areas (polygons) for up to four different layers, with the top and bottom of each layer included, eg, SFC/FL100 indicates the layer extends from the surface to FL100. The boundary of the first polygon is depicted with solid lines, the next highest layer by dashed lines, the third layer by dotted lines and the fourth layer by combined dashed and dotted lines.

Top left panel
Depicts observed (OBS) ash at the time and date displayed, eg, 14/1930Z OBS means the ash displayed was observed at 1930 UTC on the 14th day of the month.
Top right panel
Depicts the expected (forecast) location of the ash 6 hours after the time of the observed ash, eg, 15/0130Z FCST means the forecast location of the ash at 0130 UTC on the 15th day of the month.
Bottom left panel
Depicts the expected (forecast) location of the ash 12 hours after the time of the observed ash, eg, 15/0730Z FCST means the forecast location of the ash at 0730 UTC on the 15th day of the month.
Bottom right panel
Depicts the expected (forecast) location of the ash 18 hours after the time of the observed ash, eg, 15/1330Z FCST means the forecast location of the ash at 1330 UTC on the 15th day of the month.

volcano symbol The dot at the bottom of the volcano symbol represents the position of the volcano producing the ash.

The legend box at the bottom of the 4-panel map includes the same information as that provided in the associated VAA. In the example above, this includes the following information.

DTG (Date Time Group): 20141214/1949Z – the VAG was issued at 1949 UTC on 14 December 2014

ADVISORY NR:  2014/1 – advisory number 1 for 2014.

INFO SOURCE:  PIREP – the ash was reported in a pilot report (PIREP)

AVIATION COLOUR CODE:  RED – this is the aviation colour code assigned by GNS (representing the New Zealand volcano observatory).

ERUPTION DETAILS:  ERUPTION AT 20141214/1840Z – the eruption occurred at

1840 UTC on 14 December 2014.

RMK:  WINDS SW EXPECTED TO TEND W AND INCREASE 5-10KT NEXT 6-12HRS – Southwesterly winds are expected to tend westerly and increase by 5-10 knots during the next 6 to 12 hours.

NXT ADVISORY: NO LATER THAN 20141215/0149Z – the next advisory will be issued no later than 0149 UTC on 15 December 2014.
