Greetings

 

Tim, Harold and I are reporting on the activities of the August–September Intensive Flying Campaign of SAFARI 2000. First official science flights began on August 15. To date there have been 9 ER2 science flights; 17 CV-580 flights; with approximately 20 science flights each for JRA and JRB. You can access this data, as well as more detailed information, through the www.safari2000.org. This site is based here in Pietersburg and is supported by SAFARI 2000 operations.

 

We are pleased to say that the SAFARI 2000 Project data server has worked well. For those of you using a MacIntosh, please be advised that you will need to use Internet Explorer 5 to be able to utilize the Geospatial Database. On that database you will find many types of detailed information both of a predictive nature (e.g. the AVHRR quicklook fire products from GSFC; Satellite predicts for L7, Orbview2, TOMS, AVHRR and of course, Terra) to post-flight descriptions of aircraft flight paths and times.

 

In terms of maintaining the trajectory of the SAFARI 2000, S2K Operations we have done quite well in terms of observing biomass burning (both from flaming and smoldering fires), industrial (primarily power generation, metallurgical industries) and biogenic emissions (from both native and non-native vegetation). We have focused on imaging a number of ground sites linked to ground-based sites related to the EOS validation and the AERONET network. We have also accomplished a number of validation objectives for MODIS and MOPITT and now with AirMISR back on line after having been down since shortly after the start of the project, hopefully MISR. An effort has been made to combine the validation assets of the ER2 with satellite overpasses of the TOMS satellite as well.

 

We have made observations in three of the six areas that we set out at the Pietersburg workshop this past April. These areas include the industrial belt of South Africa and associated outflow region; the inflow region of Zimbabwe and Mozambique (main emphasis has been with in-situ aircraft); the region of the Okavango Delta and the western province of Zambia. Our efforts to achieve a more in-depth coverage of some of the sectors have been hampered by problems with over flight clearances that have yet to be worked out. Beginning around the 7th-8th of September, the project emphasis will shift over to the western side of the subcontinent and concentrate on subcontinental outflow and aerosol/trace gas - cloud interactions with the Namibian stratus deck. Two of the remaining three sectors - Namibia and the Karoo/Western Cape Region of South Africa/Kalahari of Botswana - will be addressed with this shift in emphasis. The Univ. of Washington CV580 will join the UKMO MRF C-130 in conducting in-situ studies in support of EOS validation as well as to obtain fundamental understanding of radiative and chemical interactions of aerosols, trace gases and clouds within that region. We are also hoping to work more closely with our Australian colleagues who will be making a number of flights well downwind of southern Africa to observe the chemical effects of African aerosol and trace gas outbreaks.

 

In terms of social and scientific outreach, SAFARI 2000 has enjoyed success through its science and aviation public open day on the 12th of August. More than 6,000 members of the local, regional and national public visited the scientific and general interest displays on that day. Subsequently, we have focused on targeting smaller groups of students, from kindergarten through graduate students, the public as well as selected government agencies.

We still have a way to go, but feel that we are on well on the path of achieving our stated objectives.

Bob Swap, Harold Annegarn and Tim Suttles
