Asa is a research station belonging to SLU and SITES.
The NordSpec measurements are done in a clear-cut area of former spruce (Picea abies). The NDVI sensors are located in a flux tower measuring CO2, operated by Lund University. There are also sensors for measuring NDVI from the ground vegetation.
Data from the sensors can be viewed online here: http://esf_klimatdata.slu.se/nordspec_asa_day.aspx.
