Cooling Degree Days
Cooling Degree Days data was reported at 5,299.960 Degrees Celsius in 2020. This records an increase from the previous number of 5,258.970 Degrees Celsius for 2019. Cooling Degree Days data is updated yearly, averaging 4,752.570 Degrees Celsius from Dec 1970 (Median) to 2020, with 51 observations. The data reached an all-time high of 5,299.960 Degrees Celsius in 2020 and a record low of 4,366.660 Degrees Celsius in 1976. Cooling Degree Days data remains active status in CEIC and is reported by World Bank. The data is categorized under Global Database’s Sierra Leone – Table SL.World Bank.WDI: Environmental: Climate Risk. A cooling degree day (CDD) is a measurement designed to track energy use. It is the number of degrees that a day's average temperature is above 18°C (65°F). Daily degree days are accumulated to obtain annual values.;World Bank, Climate Change Knowledge Portal. https://climateknowledgeportal.worldbank.org;;

Mean Drought Index
Mean Drought Index data was reported at -0.033 NA in 2021. This records an increase from the previous number of -0.930 NA for 2020. Mean Drought Index data is updated yearly, averaging -0.478 NA from Dec 1960 (Median) to 2021, with 62 observations. The data reached an all-time high of 2.012 NA in 1966 and a record low of -2.266 NA in 1990. Mean Drought Index data remains active status in CEIC and is reported by World Bank. The data is categorized under Global Database’s Sierra Leone – Table SL.World Bank.WDI: Environmental: Climate Risk. The SPEI fulfills the requirements of a drought index since its multi-scalar character enables it to be used by different scientific disciplines to detect, monitor, and analyze droughts. Like the sc-PDSI and the SPI, the SPEI can measure drought severity according to its intensity and duration, and can identify the onset and end of drought episodes. The SPEI allows comparison of drought severity through time and space, since it can be calculated over a wide range of climates, as can the SPI.;Global SPEI database (SPEIbase). https://spei.csic.es/database.html;;
