**[Additional Instruments:]{.underline}**

No additional instruments.

**VISUAL OBSERVATIONS AND GENERAL**

**[Wind direction (check correct use of the Beaufort Scale, bearings
known?)]{.underline}**

Yes the bearings are known and books are available.

**[Visibility (marks known, table on station?)]{.underline}**

Hills about 20km south of the station are used as visibility reference
point.

**[Cloud amounts, heights and types:]{.underline}** The table is
available

**[(Heights of surrounding hills known, is there a cloud book and cloud
chart on station?)]{.underline}**

Yes there is a cloud chart and heights of nearby hills are
known**[.]{.underline}**

**[Field books 301s and remarks:]{.underline}**

Available and are adequately stalked and observations are well recorded.

**[Synoptic/Metar Coding(Practical test, comments, action taken. Is more
training required?)]{.underline}**

Officers are conversant with codes. Training in climate reports
preparation. Preventive maintenance and calibration of instrument short
course are need.

### Supplies, are there adequate supplies on station?

1 year supply is always ordered in advance.

[I**nstrument care, management and maintenance: **]{.underline}

Maintenance of instruments is done once in while.

**[Sketch, photograph and horizon profile of site:]{.underline}**

See attachment.

**[Are hydrogen and balloon filling procedures being correctly
followed]{.underline}**

No upper air is being done at the present time however; preparations are
being made to start upper air observations next year, probably the first
quarter of the year.

**[Other items and general remarks on impression and ability of
observer(s):]{.underline}**

The station is well maintained, however there are very few instruments.
The observers have the necessary training but they need some training to
enable them to fully understand the importance of their work.
