BodEx 2005 - Measurements and observations in northern Chad (Bodélé/Djourab)


We thank, above all, the Gilchrist Educational Trust for funding our expedition, and Professor Sir Ron Cooke and Dr Ina Tegen for supporting our application. We must also thank the Dean's Fund and the Department of Geography at University College London, and our Departments in Oxford and Salford for additional funding.

We had excellent cooperation from officials in Tchad for which we are very grateful. This includes the help given to us by the Direction des Eaux et de la Météorologie (who allowed Samuel Mbainayel to come with us, and who stored our equipment for a few weeks); Dr Baba El-Hadj Mallaye, of the Centre national d'Appui à la Recherche for his interest and invitation; and Dr Dehainsala Waleyam, of the Direction de la Recherche Scientifique et Technique for his "Autorisation de Recherche". Madame de la Croix, the British Honorary Consul could not have been more helpful, and nor could Mahamat Abrerahman Troumba.

For helping us with equipment, we thank:

  1. NASA Climate and Radiation branch (Vanderlei Martins) for supplying nuclepore dust sampler and subsequent laboratory analysis and Zhara for bringing the instruments from the USA.
  2. NASA Aeronet (especially Wayne Newcomb and Mikhail Sorokin) for the calibration of Cimel c-318, processing of data and repair of dust damage to instrument.
  3. NERC EPFS for the loan of the Microtops.
  4. Jim Haywood at UK Meteorological Office for processing of the Microtops data.
  5. Andrew Wilson at Centre for Ecology and Hydrology, Monks Wood, for the loan of the Cimel.
  6. Phil Anderson and Russ Ladkin at British Antarctic Survey for the loan of the radiosonde and its later repair.
  7. Mike Jensen at the University of Colorado, Boulder for supplying the meteorological kite and tether.

We are indebted to Dr Nick Drake (KCL) for his generosity with satellite imagery and Digital Terrain Models of the Bodélé, and access to his analyses of these.

Finally we thank Jim Giles from Nature, who showed great interest in the field and has written a valuable article about our expedition.
