About these charts

Weather has a great impact on the growth of turfgrass. The carbon dioxide uptake that occurs in the photosynthesis of managed turfgrass is influenced by four primary factors: light, temperature, water, and nitrogen. Turfgrass managers are able to modify the plant water status and the leaf nitrogen content, but there is very little that can be done about light or temperature. With charts that show the average temperatures and sunshine hours, these uncontrollable factors and their seasonal influence on turfgrass growth can be easily observed.

These charts have been developed by the Asian Turfgrass Center to provide a guide to the climatological normal data for many locations around the world where warm-season (C4) grasses are grown. These charts can provide an indication of which grasses may perform best in certain regions and when certain maintenance practices are likely to be most effective for a grass at a specific location.

On Data, Charts, and Software

Data shown on these charts are from the World Meteorological Organization and, in the case of the Japan motion chart, from the Japanese Meteorological Agency.

The static charts were made using the ggplot2 package in R. Motion charts were made using the googleVis package in R. This document explains the procedure I used to make a motion chart with data from 52 world cities.
