ABoVE Data Measure Arctic Greening

MODIS and CCaN average growing season

MODIS (left) and CCaN (right) average growing season NDVI.

A new study of long-term NDVI trends across the North Slope of Alaska presents high-resolution growing-season NDVI from MODIS.

Long-term Mean Leaf Area Index

Leaf area Index for July

Mean leaf area index for July (calculated over the period 1982-2015).

A global dataset characterizes the long-term (1981-2015) monthly mean Leaf Area Index (LAI) based on AVHRR GIMMS data.

Vegetation Changes Along Alaskan Rivers

Yukon River riverbank erosion and vegetation colonization

Riverbank erosion and vegetation colonization at the Yukon River 1 study area, located along the Middle Yukon River between Circle and Fort Yukon, Alaska, from 1985-2017.

Research from NASA's ABoVE campaign provides a record of riverbank erosion and vegetation colonization along major Alaskan rivers from 1984 to 2017.

Climate and Productivity of Arctic Tundra

Arctic tudra MaxNDVI biweekly mean

Arctic biweekly NDVI (green bars) and trend (grey bars) for full tundra for 1999-2015. Biweekly trends statistically significant at the 95% level or greater are marked with an asterisk on the x-axis. From Figure 9 (c) Bhatt et al. (2017) (see dataset documentation).

NASA's ABoVE provides standardized data on potential climate drivers for productivity of Arctic tundra vegetation.
