30+ years of LAI and FAPAR data for Your research use

выдается бесплатно, то есть даром. Если надо, переведу, но попозже, сейчас работой обложили
Dear Colleague,

We are providing you free access to a 30+ year long global data sets of vegetation leaf area index (LAI3g) and fraction vegetation absorbed photosynthetically active radiation (FPAR3g). These data sets were derived from the third generation GIMMS NDVI3g data set (hence the suffix "3g"). The data sets are at 1/12 degree resolution, 15-day composites (2 per month) and span the period July 1981 to December 2011. A set of neural networks were first trained on best-quality and significantly post-processed MODIS LAI and FPAR products and AVHRR GIMMS NDVI3g data for the overlapping period (2000 to 2009). The trained neural networks were then used to produce the LAI3g and FPAR3g data sets.

You can download the LAI3g and FPAR3g data sets together with documentation and a research article (plus supporting material accompanying the article) from the links to our dropbox location below my signature. Please note the following:

(1) If you wish to submit an article to the special dedicated to NDVI3g/LAI3g/FPAR3g of the open source journal "Remote Sensing" you are welcome. The link is:

(2) These data sets, plus the NDVI3g data set when approved for release by Dr. Tucker, the special issue articles, codes and other documents will be posted at NASA Earth Exchange (https://c3.nasa.gov/nex/)

(3) For all information, please email rmy...@bu.edu

Sincerely,
Ranga B. Myneni

Data and Codes

30+ Year LAI and FPAR Data Sets: We are providing free access to a 30+ year long global data sets of vegetation index (NDVI3g), leaf area index (LAI3g) and fraction vegetation absorbed photosynthetically active radiation (FPAR3g). The data sets are at 1/12 degree resolution, 15-day composites (2 per month) and span the period July 1981 to December 2011.The links to these data sets are in this file.

P.S. Статья о которой говорят во 2 ссылке похоже вот эта.

Т.к. она Open access но приложу ее к посту.

Уф. нервы шалят. Разобралась ))
Вопрос аннулирую. Пусть просто тогда в качестве обновления инфы будет.
