The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) is on the agenda for this week’s Spring Science Meeting of the Land-Cover / Land-Use Change (LCLUC) Program (http://lcluc.umd.edu/meetings.php?mid=45
). The three-day meeting is being held in Rockville, Maryland. Dr. Suhung Shen, representing the GES DISC, will be giving a presentation on the GES DISC’s activities in support of the Northern Eurasian Earth Science Partnership Initiative (NEESPI) and the Monsoon Asia Integrated Regional Study (MAIRS).
Shen’s poster presentation, entitled “Visualization and Analysis of Multi-Scale Land Surface Products in Giovanni Portals,” describes two dedicated data portals in the NASA Giovanni data analysis system created for NEESPI and MAIRS. The two data portals feature several types of land data, including vegetation indices, surface temperature, snow cover, land cover type classifications, and even nighttime lights, which are useful as indicators of urban extent. One degree and 5.6 kilometer (km) spatial resolutions are available globally, and 1 km spatial resolution data are provided for the Monsoon-Asia region. Data are available at 8-day, monthly, and annual temporal resolutions, although not all of the data products are available at each of these temporal resolutions. Co-authors for this poster are Steven Kempler and Irina Gerasimov.
The poster uses three case studies to illustrate applications of these data: a severe summer heat wave in July 2010 in Europe; early spring 2012 temperature and vegetation anomalies in North America; and a data comparison over China spanning a decade, showing temperature and nighttime light changes at 1km resolution.
The poster also illustrates the increasing number of users of these data portals in the Giovanni system, and the increasing number of Giovanni visualizations created by these users, since January 2009.
