Input data specification

The app only accepts a comma-separated values (csv) file containing exactly one header row with column names following the convention in the table below. The dataset cannot have missing values of any kind (e.g. -999, NaN, null). Data needs to be in metric units. To simplify the data upload process, we provide an example file that you can download and fill in with your own data.

CSV header name	Data type	Example	Description
year	YYYY, integer	2016	Year
month	MM, integer	01 (e.g. January)	Month of the year
day	DD, integer	31	Day of the month
minAirTemperature	Float	8.4	Minimum air temperature at about 2 meters height in degrees Celsius
maxAirTemperature	Float	35.4	Maximum air temperature at about 2 meters height in degrees Celsius
solarRadiation	Float	18.5	Daily solar radiation in megajoules per square meter
