Precipitation, air temperature, and radiation are the most dominant meteorological factor for the vegetation distribution and its interannual change. For example, lack of precipitation precludes vegetation in desert in mid-latitude, while lack of temperature constrains the vegetation in high-latitude tundra zones. The cloud cover disturbs the potential photosynthetic activity of the vegetation by reducing the Photosynthetically Active Radiation (PAR; (0.4 - 0.7 μm)) from the sun. This vegetation-atmosphere relationship was examined by using satellite-derived Normalized Difference Vegetation Index (NDVI) data and meteorological data. The interannual correlation coefficients between NDVI and temperature; NDVI and precipitation; and NDVI and PAR from 1986 to 1995 are globally mapped.

We examined the 10-year (1986 – 1995) time series of yearly precipitation, temperature, PAR and NDVI in 1 x 1 degree grid cells over the global terrestrial area. As for precipitation, temperature, and PAR, seasonal mean values over the growing season (April to August in the Northern Hemisphere; October to February in the Southern Hemisphere) of each year were calculated based on monthly values obtained from the International Satellite Land Surface Climatology Project (ISLSCP) Initiative II dataset. As for NDVI the seasonal mean value in the growing season of each year was calculated from the monthly NDVI of a global 20-year NOAA/AVHRR dataset with 4-minute resolution produced by Chiba University, Japan (CEReS, 2001). This 4-minutes NDVI value was resampled into 1 x 1 degree grid system to match other meteorological values from ISLSCP Initiative II dataset.
The 10-year interannual correlations between NDVI and precipitation, NDVI and temperature, and NDVI and PAR was calculated. To improve the statistical significance level, those correlations were calculated base on 40 samples by aggregating 4 gird cells (i.e. 10 years x 4 grid cells). By this process the horizontal resolution was reduced to 2 x 2 degrees.
