Volcanic eruptions eject large amounts of material into the atmosphere, causing temporary cooling and less interannual variability. Some of these effects can persist for years and decades after the eruption. Unfortunately, very few instrumental records are available for the Mount Tambora eruption in 1815, the largest eruption in the past several centuries. This study uses proxy records from historical documents to study changes in inter-annual variability. We use plantation documents from two locations that cover the period 1764-1873. These records include ordinal observations of weather conditions. They also contain extensive phenological records for local as well as common agricultural species. The relationship between phenology and aspects of climate are exploited as a proxy to reconstruct micro-climate changes in inter-annual variability in response to volcanic forcing.
