What is NEESPI?NEESPI Northern Eurasian Earth SciencePartnership InitiativeWhat is this Initiative about? NEESPI is designed to establish an international, large-scale,interdisciplinary program aimed at developing a better understandingof the interactions between the terrestrial ecosystem, the atmosphere,and human dynamics in Northern Eurasian.What are NEESPI goals? To conduct a large-scale, interdisciplinary program of fundedresearch aimed at developing a better understanding of theinteractions between the terrestrial ecosystem and the atmosphere,with a special emphasis on the human impacts and feedbacks innorthern Eurasia in support of international Earth science programswith particular relevance to global climate change research interests(including carbon) and international sponsoring agency fundingpriorities.July 2008G. Leptoukh, IGARSS08, Boston3

What is the NEESPI study area? The NEESPI study area is loosely defined as the region lyingbetween 15 E Lon in the west, the Pacific Coast in the east, 40 NLat in the south, and the Arctic Ocean coastal zone in the north. Includes territories of the former USSR, Fennoscandia, EasternEurope, Mongolia, and Northern China. All landscapes and components of the terrestrial biosphere,including the hydrology and atmosphere, that are interactive forpurposes of Earth science investigation (to include the humanimpacts) are considered a part of NEESPI study area.July 2008G. Leptoukh, IGARSS08, Boston4

What ecosystem types are in northern Eurasia?The vast territory encompasses: peat bog-tundra, forest tundra and borealforests in the north forests and agriculture at the mid-latitudes forest-steppes, steppe, agriculture and aridzones in the south lakes, ice, and coastal zones throughout theregionJuly 2008G.

Giovanni and GISGiovanni can be accessed in a machine-to-machineway via Web Mapping Service (WMS) and WebCoverage Service (WCS) protocols. Giovanni can act as WMS or WCS server, thusallowing any GIS clients to add layers or get subsetteddata from Giovanni. Giovanni also can act as WCS client by gettingremotely located data via WCS.July 2008G. Leptoukh, IGARSS08, Boston21

Increased precipitation during spring of 2002 induced anincrease in plant productivity and the corresponding NDVI signal. The enhancedplant productivity potentially leads to a greater accumulation of fuels. Fuelaccumulation results in increased fire occurrence (observed through Fire Counts)during fall season.July 2008G.

Conclusion of the Russian Fire East firedanger exploration example A large number of fires detected in July of 2003 – a nearly 200-time increasein fire detections compared to other years during 2001-2006. despite thesummer monsoon suppression of large fire occurrence.Traditional vegetation indices (NDVI and EVI) included in operational firedanger assessment provide little information on the fuel state in this ecosystempre- or post-fire.No considerable differences in surface temperature and soil moisture in Julywere observed between the catastrophic year of 2003 and the two subsequentyears of low summer fire occurrence of 2004 and 2005.However, the temporal analysis indicates that dry spring conditions in 2003(detected through low soil moisture measurements in April and May) mayhave led to a stressed vegetative state and created conditions conducive tocatastrophic fire occurrence.July 2008G.
