SAFARI 2000 Newsletter, No. 3, version 1 (November 22,2002)
Greetings to Registered SAFARI 2000 Participantsand Other Interested Parties,
There are several new items of interest describedin the links below.
The SAFARI Newsletter is published on an ‘as needed’basis, thus the large gap since our last newsletter. The Newsletter will be postedsoon with the other newsletters on the SAFARI 2000 web site in South Africa (http://www.safari2000.org) under the ënewsletterí link in the ëregistered userí area.
SAFARI Volume 2 CD-ROM available! NASA’s SAFARI Data Team has just completedthe second in a series of three planned CD-ROM volumes containing data from the SAFARI2000 region of southern Africa. The data on this second volume (5 discs) includeobserved and modeled meteorological data, aerosol measurements, and precipitationdata, as well as a large collection of aircraft and MODIS Land and Atmosphere productsfrom the Dry Season campaign. The new volume interacts seamlessly with the last yearísVolume 1 data sets. Volume 2 was first distributed to attendees of the SAFARI SynthesisMeeting at the University of Virginia in October. The CD’s are now available to registeredparticipants upon request from the SAFARI data centers (ORNL DAAC and Wits/NDMC).
In the US and EU, this CD-ROM archive can be orderedfrom:
In the southern Africa region, this CD-ROM archivecan be ordered from:

SAFARI 2000 Synthesis Meeting atthe University of Virginia The SAFARI 2000 Synthesis Workshop, heldin Charlottesville, Virginia, from October 7ñ11, 2002, was focused on the analyses,results, and working group discussions of the key SAFARI findings to date. The workshopprovided an opportunity for scientists involved with both the SAFARI 2000 Wet Seasonand the Dry Season Campaigns to interact and to make key contacts with respect tothe development of Phase II science questions (i.e., from post-data collection andinitial analysis into synthesis activities).
The SAFARI 2000 community was challenged both byDr. Diane Wickland, NASA Program Manager, and by the Honorable Rejoice Mabudafhasi,South African Deputy Minister of Environmental Affairs and Tourism, and Chair ofthe African Process, to relate, in plain terms, the SAFARI agenda and accomplishmentswith respect to the goals of the program managers, government administrators, andother policy makers.
The working groups focused on the following issues:
What do we know now as a result of SAFARI 2000 thatwe didnít know before?
What currently funded analytical efforts are underwayregarding SAFARI 2000 and what types of products are expected?
What next science efforts are needed over the next12 months or so to enable project-wide synthesis?
What can the SAFARI 2000 community say that relatesto issues of natural resource management, air quality and fire management in southernAfrica?
What can be done to keep southern African scientistsplugged in to larger international programs during the post-field campaign phaseof SAFARI 2000?
Participants broke into one of three large workinggroups: 1) Fire, Fuel and Emissions; 2) Ecosystem Processes; and 3) Aerosols, TraceGases, Clouds and Radiation. Summary Reports from the groups indicated that muchhas been learned about the physical, chemical and biological characterization oftheir respective systems along gradients of ecosystem and land use types in southernAfrica since the previous large scale science initiative in 1992 (Southern AfricanFire-Atmosphere Research Initiative ñ SAFARI-92). Participants stressed the needfor a greater involvement of the atmospheric chemistry modeling community and theirinterfacing with current SAFARI 2000 modeling activities to aid in the drive towardsproject synthesis.

4th SAFNet Meeting, Kruger NationalPark, South Africa, 17-22 August 2003. The Southern African Fire Network (SAFNet)is a non-funded regional network of African scientists, government workers, NGO members,etc., with strong interests in long-term fire information to support research andoperational agendas in resource management, environmental assessment and global changeresearch. SAFNet’s goal is to achieve more effective and appropriate fire managementpolicies and practices in southern Africa through the use of remote sensing and othergeospatial information technology. See http://safnet.umd.edu/ forfurther details.
Status of SAFARI 2000 Special Publications There are currently four special publicationsunderway highlighting results of SAFARI investigations.
Journal of Geophysical Research
There are 36 accepted articles to date, with a fewmore that may make it in before the deadline as the overview article is being prepared.This special issue is being co-edited by Harold Annegarn and Bob Swap.
International Journal of Remote Sensing
Thirteen manuscripts were submitted to the SAFARI2000 Special Issue of the International Journal of Remote Sensing. The editors havemailed reviewer comments to the authors in most cases and expect all review and acceptanceto be completed by early to mid-2003. This issue is being co-edited by Jeff Privetteand David Roy.
Journal of Arid Environments
Thirteen articles, including eight related to theKalahari Wet Season Campaign, will be published in a special issue of the Journalof Arid Environments. The editors expect publication by the yearís end. The co-editorsfor this issue are Prof. Raban Chanda and Dr. Otlogetswe Totolo.
Global Change Biology
Eleven papers have been accepted for an upcomingGlobal Change Biology special issue related to SAFARI 2000. The issue is focusedon the presentation of ecological information about the Kalahari Transect resultingfrom IGBP Kalahari Transect and SAFARI 2000 Wet Season Activities. The lead editorsfor this issue are Hank Shugart and Steve Macko.
Feedback on CD-ROM Volume 2 We need your feedback on the SAFARI Volume2 CD-ROM. In particular, we would like your assessment of the modeled meteorologicalproducts from the GSFC Data Assimilation Office (DAO). These are global 1-degreedata that were processed by the Goddard DAAC specifically for SAFARI. First, thedata were spatially subsetted for southern Africa. The data set on the CD containsa subset of 56 parameters that we deemed most useful from a large list of availableparameters. The DAO data are comprised of surface parameters as well as atmosphericparameters that are available at multiple pressure levels. The data on the CD containa subset of the pressure levels available. The surface parameters are available at3-hour intervals, and the atmospheric parameters at 6-hour intervals.
Due to large data volume, the DAO data included onVolume 2 spans just two months, the August/September 2000 to support the Dry SeasonCampaign. We will make decisions on what DAO data to include on Volume 3 based onyour feedback and preferences. As noted above, there are many options available forcustomizing these data, all of which require resources of the Goddard DAAC and theSAFARI data team. We can provide a larger temporal sequence of data on the CD, suchas a 3-year sequence, by limiting the parameter set, pressure levels, and temporalfrequency of measurements. Please provide us with feedback so that we can betterfulfill the needs of the SAFARI community.
TFRIC Expands SAFARI Satellite DataArchive The SAFARI 2000 Landsat ETM+ data archivecontinues to grow, with about 170 Landsat ETM+ scenes now available over southernAfrica. Additionally, our 1990’s-era TM GeoCover ™ data set contains wall-to-wallorthorectified TM coverage of southern Africa. Space Imaging IKONOS data sets acquiredfor SAFARI Core Sites can also be ordered from TRFIC. In addition, TRFIC site hasan excellent tool for Landsat-7 data browsing.
MODIS News A second MODIS sensor was launched into spaceon May 4th onboard the Aqua platform. Aqua views the sunlit side of Earthin the afternoon (Terra views sunlit Earth in morning). Early MODIS/Aqua data areexcellent, and the lessons learned from Terra have resulted in a much faster onsetof product generation. The MODIS Team continues to improve the calibration of raw data and refine the algorithmsfor derived products. A complete reprocessing of the MODIS-Terra data set will commencein December, starting with data acquired in Feb. 26, 2000 (thanks in part to theSAFARI Wet Season Campaign!). The results of this reprocessing will be referred toas “Collection 4” and will be indicated in the file names by the .004field. For the Level 3 and higher Land products, this reprocessing will constitute a majorchange in that the products will be projected to a Sinusoidal grid, as opposed tothe Integerized Sinusoidal (ISIN) grid used previously. Most commercial image analysissoftware reads Sinusoidal data. The reprocessing will produce the standard MODIS1200 km by 1200 km tiles available through the EOS Data Gateway (http://edcimswww.cr.usgs.gov/pub/imswelcome/). The reprocessing willlead to new 200 km by 200 km subsets extracted for the SAFARI 2000 Core Sites, availablethrough the South African National Disaster Management Centre (follow http://sandmc.pwv.gov.za-> “Activities: NASA-WITS-NDMC”-> MODIS). Note: Standard data and subsets from the MODIS-Aqua platform are anticipated to beavailable by the end of 2002.
Final SAFARI CD-ROM — Submit Your DataSets and Modeling Results Data collection for the Volume 3 CDROM isalready underway, with CD production tentatively scheduled for late 2003. This collectionwill represent the final opportunity for data collectors and modelers to submit datafor publication on the SAFARI CD-ROM Series. Ground data measurements from the wetseason are especially anticipated as they have thus far been underrepresented onthe CDs. Volume 3 will also accommodate updates of data from earlier volumes, aswell as any other SAFARI data sets. Sharing your data on SAFARI CD-ROMs affords theadvantage of expanded opportunities for collaboration with little additional costor effort. In addition, the NASA Data Team is ready to work with you in developingdocumentation, metadata and proper data formats. This help will not be availableafter 2003.
We urge all participants to finalize their data setsand submit them to this final CD-ROM. The SAFARI 2000 Project succeeds only if participantshonor the agreement outlined in the Data Policy, particularly the sharing of dataor results with all SAFARI participants.
Many participants have already signed up to submittheir data for Volume 3 according to the list below. If you are not listed belowbut have data that you would like to see included on this final volume, pleasecontact Jaime Nickeson (Jaime.Nickeson@gsfc.nasa.gov).
