The Global Warming Potential GWPP) of Estonian rural land-use types (42,685 km2) from potential CH4 and N2O fluxes is 5.99 million t of CO2 equivalents, of which N2O is responsible for 86%.
Population density estimates were calculated using the highest resolution administrative unit for which data are available in Kenya (ward) for population and ward area (km2) from the Society for International Development and the Kenya National Bureau of Statistics (herein, "SID-KNBS") (2009).
The observed landslides from the Virginia earthquake enclose an area of about 33,400 km2, while previous studies indicated an expected area of about 1,500 km2 from an earthquake of similar magnitude.
Lightning, the other major cause of ignitions, was assessed using the NASA Global Hydrology and Climate Centre Lightning Team's high resolution annual lightning climatology which reports annual flash rates per km2 from data collected between 1995 and 2005 [34].
