SMNH/IRI Honduras Historical Temperature Monitoring

The Maproom explores historical daily temperature by calculating simple seasonal statistics.

Many options can be specified to produce yearly time series of a chosen seasonal diagnostic of the daily temperature data. The user can then choose to map the mean, standard deviation or probability of exceeding a chosen threshold, over years; clicking on the map will then produce a local yearly time series of the chosen diagnostic.


Years and Season: Specify the range of years over which to perform the analysis and choose the start and end dates of the season , over which the diagnostics are to be performed.
Seasonal Data Coverage: A minimum fraction of non-missing days per season can be required in order for the seasonal diagnostic to be defined at that station — if this minimum threshold is not met, then the seasonal diagnostic is assigned a missing value at that station, for that season and year.
Hot/Cold Day Definition: This threshold is used to define in Celsius degrees (non inclusive) the temperature under which a day is considered cold if the minimum temperature is below it; or the temperature above which a days is considered hot if the maximum temperature is above it; or the reference temperature for to compute the heating degree days.

Seasonal daily statistcis: Choose the seasonal diagnostic quantity (i.e the statistic of the daily data) to be computed for each season, from the following choices.
Mean, Minimum and Maximum Temperature: average mean, minimum or maximum daily temperature over the season.
Heating and Cooling Degree Days: Heating/Cooling degree days are summations of negative/positive differences between the mean daily temperature and user-defined reference base temperature during the season. The mean temperature is defined as the average of the minimum and the maximum.
Number of Cold and Hot days: the number of cold or hot days during the season according to the user-defined threshold and according respectively to the minumim temperature and the maximum temperature.
Percentage of Data Available: the percentage of days with non missing values within the season.

Yearly seasonal statistics: a choice of yearly statistics over the chosen season of the selected range of years to produce the map among: the mean, the standard deviation, the probability of exceeding a user specified threshold, the coefficient of variation and the value of a user specified percentile.
