Abstract:
A suite of parallel meteorological measurements were undertaken over the extended period 1884-1903 at the Royal Alfred Observatory in Mauritius. The data were observed in: a well-ventilated room, by means of a Thermograph in a dedicated building, in a Stevenson Screen and by a Hygrometer in a different Stevenson Screen both in an enclosure, and for a short period two additional Stevenson Screens. Data were recorded in a series of annual reports from the observatory - two forms of which were produced each year. However, only a subset of these reports have been found. Data have been transcribed as monthly summaries of maximum, minimum, average (of certain hours) and mean (of max/min). The latter have been computed from max and min where not directly reported. All values are in the originally reported Fahrenheit values. Data were transcribed for a masters thesis by Samuel Awe and supplemented by subsequent transcriptions by Peter Thorne.

Comment:
All values in this dataset were recalculated from Fahrenheit to °C via (°F-32)/1.8
-----------------------------------------------
Instrument configurations:
Room - well ventilated room in the SE corner of the observatory building
Thermograph - Thermograph housed in a dedicated building with a south facing aspect
Stevenson - Stevenson Screen in an instrument enclosure
Hygrometer - Hygrometer mounted in a Stevenson Screen within the same meteorological instrument enclosure
Stevenson at 6ft - a Stevenson Screen that for a short period was mounted in the same instrument enclosure but was at 6ft (1.8 m) height
Large Stevenson - a Stevenson Screen that for the same period of time was also present but had a larger (closer to modern day) Screen shelter size
