Shiny application for finding weather data for any pixel using WorldClim data

Brief data summary

Shiny application uses the API of WorlClim data set for getting climate data with coordinates taken by clicking on an interactive map or by typing on a text box. The applications uses WorldClim version 2.1, which contains monthly averages data calculated with climate data from 1970 to 2000, the resolution of data is available for three resolution size: 4.6km (2.5 minutes), 9.2 km (5 minutes) and 18.5 km (10 minutes). monthly averages. Each data represents a square surface (called pixel), which length per side is the resolution mentioned above. Elevation data is also available, derived from SRTM elevation data.

The application is for finding average weather data for a single pixel at either 5′, 10′ or 25′ (minute) resolution. It is not for bulk downloads.

Data availability

The data can be accessed through a server at the International Maize and Wheat Improvement Center (CIMMYT).

The climate variables available for downloading are:

• Maximum temperature.

• Minimum temperature.

• Mean temperature.

• Rainfall.

Elevation data is also available, derived from SRTM elevation data, for the same resolution mentioned above.

Underlying data sources

The underlying data is from the WorldClim weather and climate database.

Accessibility

Metadata

The data is presented in CSV format. The file title indicates the variable and the resolution. Inside the file we observe the average values per month as displayed on the webpage.

Note that the coordinates are currently not provided in the downloaded file. The user should note them down if required.
