The description consists of 11 sections broken down into three main areas: General Description,
Site Description and Station Description; m uch of this inform ation is required for the Archive, but it
is set up as an information package for prospective data users. A description of the information
required to complete the package follows. A blank document is included in Annex A.
3.2.1 General Description
(1) Information on whom the scientific authority is for the site. Postal address, telephone, fax
and E-mail if applicable.
(2) The site’s location: latitude (N positive 0 - 90), longitude (East/West of Greenwich),
Elevation above MSL, Local Time from GMT, Station Topography and Station Surface
Type from the archive, and the date of the first data submitted to the archive.
(3) Topographic map showing the land within a 15 km radius. A topographic map with a
scale of approximately 1:250000 provides the appropriate resolution. This gives users a
sense of the homogeneity of the surrounding areas.
3.2.2 Site Description
(4) Site Surroundings: a written description indicating population centres, population
density. When the station is within a large city, the following information should be added
to the description: whether the city is growing, stagnant or declining in population. Major
sources of pollution. Large bodies of water or significant local topographic effects should
be noted. If the site is located at an educational institution or on the top of a building.
(5) Climate characteristics: the general clim ate type (e.g., m aritim e, polar, etc.), climatic
normals (min/mean/max summer/winter temperatures, mean rainfall etc.), significant
climatic events (e.g., monsoons, hurricanes, tornadoes)
(6) A map of the local area around the station (approximately a 1 to 2 km radius). A recent
topographic map or photomap with a scale of 1:50000 provides the necessary resolution.
3.2.3 Station Description
(7) A list of all the radiation fluxes being measured routinely at the station and the types of
instruments being used. The type of data acquisition system(s) being used, the sampling
rates of the data acquisition system and the outputs that are being archived. Information
on the tracking and shading systems that are being used in obtaining the m easurements
is also required.
(8) A station map: a detailed map indicating the location of the individual sensors in relation
with each other. This map is primarily for the radiation instrumentation locations and
need not include the location of the meteorological station or upper air station. Such
information would be on the station map if the distances were greater than approximately
20 m.
(9) A horizon view of the global radiation sensor indicating the m ajor obstructions. This
would be a figure utilizing the data supplied to the Archive running from North through
South to North in a clockwise direction.
(10) Comments on the site. For example, comments would include the instrumentation and
data acquisition systems that are used for the meteorological variables. If another
individual is the responsible contact for the meteorological portion of the site, the name
and address would be included in these comments. A brief description of the method
and frequency of the calibration of the sensors would be included in this set of
comments. If a particular set of research measurements were being made at the site,
this should be noted and the name and address of the appropriate contact given. This
section can be used by the site manager to advertise anything that makes the particular
site special.
