LANCE users span a variety of communities interested in a range of applications. Users come from both the civilian and military sectors, from government and non-government agencies and from universities and other research intuitions. This section highlights a selection of LANCE users.
Global Fire Information Management System (GFIMS) - GFIMS is an operational version of FIRMS running at the United Nations Food and Agriculture Organization (UN FAO) where it complements the FAO’s existing suite of projects that deliver near-real time information to ongoing monitoring and emergency projects, to other UN organizations as well as providing information to the general public.
Global Observation of Forest and Land Cover Dynamics (GOFC-GOLD) - The GOFC/GOLD-Fire Mapping and Monitoring Theme is a project of the Global Terrestrial Observing System (GTOS) program, aimed at refining and articulating the international observation requirements and making the best possible use of fire products from the existing and future satellite observing systems, for fire management, policy decision-making and global change research.
UN Global Fire Monitoring Center also provides MODIS-based fire data for the international fire community.
US Forest Service Remote Sensing Applications Center (RSAC) - RSAC produces daily regional fire maps based on data from MODIS Rapid Response and their regional Direct Broadcast antenna.The maps are distributed through the National Interagency Fire Center, which coordinates all the national and regional fire agencies across the United States. The maps are used to allocate firefighting resources during the fire season. The Rapid Response staff also supplies the Forest Service with science software to generate rapid fire products from the MODIS data collected regionally by their Direct Broadcast antenna.
Advanced Fire Information System (AFIS) – AFIS is a comprehensive wildfire information system that provides users with information and intelligence around the prediction, detection, monitoring and assessment of wildfires globally. Earth Observing satellite wildfire detections are complemented with both crowdsource detections from the AFIS Watchtower app as well as through automated in situ camera detection systems capable of detecting thin smoke plumes up to 20 miles away. Fire Danger models such as the Canadian Fire Weather Index (FWI) and Australian McArthur Fire Danger models have been fully integrated in to the system and can be produced for any area globally. A new MODIS burned area product has been produced by merging the standard MCD45 MODIS with the MCD64 Burned Area product while a new Landsat 8 and Sentinel 2 algorithm has also been developed to provide higher resolution mapping of new fire events. AFIS provides a hybrid wildfire dashboard providing situational awareness for any region of interest and integrates NASA Worldview into the dashboard to improve the visualization component within the dashboard and now provides users with access to not only the Direct Readout station data but also all the NASA GIBS data sets.

The US Department of Agriculture’s Foreign Agricultural Service (USDA FAS) uses NRT MODIS imagery from LANCE to observe large areas across the world. These images help FAS improve the accuracy and timeliness of the crop yield predictions, which are needed to make decisions affecting U.S. agriculture, trade policy, and food aid. MODIS collects data twice daily, from the Terra satellite in the morning and the Aqua satellite in the afternoon, which helps analysts observe how events such as fires, volcanic eruptions, floods, storms, or extreme temperatures affect crops.
Global Agricultural Monitoring (GLAM), a collaborative project between the University of Maryland, USDA FAS and NASA uses NRT MODIS to produce crop masks and timely NDVI products that allow FAS analysts to distinguish between different crops like wheat and rice and predict yield by comparing current data with previous years.
The United States Air Force Weather Agency and the U.S. Naval Research Laboratory rely on MODIS Rapid Response images to monitor and predict dust storms in the Middle East and Southwest Asia. Dust storms can interfere with troop and equipment movement and with aircraft safety. The military also uses NRT time imagery for other areas in the world where weather conditions, snow cover, smoke, fires, volcanic eruptions, and other things could impact military operations.The US Environmental Protection Agency and the US Naval Research Laboratory monitor for smoke that might be a health threat.
Aerosol Robotic Network (AERONET) - AERONET is a worldwide network of ground based sensors that monitor the air for aerosols to understand the impact of aerosols on climate change. LANCE provides NRT MODIS imagery of the sensor sites. By comparing satellite and ground-based observations, scientists can learn how aerosols reflect and absorb light and can validate satellite-based aerosol observations. This will improve the tools scientists use to monitor aerosols over the entire Earth.
The British Antarctic Survey uses MODIS NRT imagery to help navigate sea ice and to populate Polar View, a website that delivers information about sea ice extent and icebergs directly to ships operating in the Southern Ocean. Users of Polar View in the Antarctic include national program operators, tourist vessels and other ships working in this region. The aim of Polar View is to make sea ice information widely accessible to all ships and operators in the Southern Ocean.
The Polar Geospatial Center (PGC) uses NRT MODIS imagery to flag significant polar events, this information is used task higher resolution imagery. PGC also harvests MODIS NRT imagery to add to its collection of satellite imagery supporting researchers and logistics groups in the polar science community. Timely data is used to support the US Antarctic Program. The images are used to plot new courses for the Coast Guard icebreaker and fuel and cargo ships bringing supplies to McMurdo Station, the American research station on Antarctica. Daily images are crucial to chart a safe course around the drifting icebergs and through the sea ice that covers McMurdo Sound. The images are also being used by scientists who are tracking the movement of the icebergs.
As LANCE can create an image of an event such as a major fire the same day it happens, the images are ideal for news and outreach. Rapid Response provides regular images of storms, fires, and other events as they happen to the NASA Public Affairs Office and the media. MODIS Rapid Response images have been featured in major newspaper and television networks across the world. NASA’s Earth Observatory web site posts regular MODIS images of significant events around the world in the Natural Hazards section and as Image of the Day. MODIS Rapid Response images have also appeared on the NASA portal, the Goddard Space Flight Center home page, and on Goddard TV.
The American Museum of Natural History incorporates MODIS Rapid Response images into a regularly updated exhibit about the Earth called Science Bulletins. Displayed on interactive kiosks and on high-definition video, the Science Bulletins provide a way for museums to exhibit stories and information about current science, and are intended to show that science is dynamic with new discoveries being made constantly. There are three Science Bulletins: Astro Bulletin, which is about astrophysics and astronomy, Bio Bulletin, about biodiversity and conservation, and Earth Bulletin, about Earth and climate. In addition to being displayed at the American Museum of Natural History, the Bulletins are also made available for display to other science museums, universities, and NASA visitor centers around the United States and Canada. Currently, 21 institutions are participating. The Bulletin sites offer additional information, not available in the exhibits, as well as an archive of past Bulletins.
User Working Group
LANCE is reviewed and supported by a User Working Group (UWG) whose members reflect the various user communities served by LANCE as well as representatives of the Science Teams for the five LANCE instruments. The group is chaired by Professor Chris Justice, Chair of the Department of Geographical Sciences, University of Maryland, College Park. The UWG meets at least once per year to review the status of LANCE operations and development activities and to provide guidance concerning future upgrades suggested by the user communities and the LANCE elements. Details of the responsibilities of the UWG are given in the User Working Group (UWG) Charter.
More information about the User Working Group can be found on the LANCE wiki.
