Notes that, despite the progress made, only limited advances have been made in achieving long-term continuity for several in situ observing systems and that there are still large areas, in Africa for example, for which in situ observations and measurements are not available;
3. Note qu &apos; en dépit des progrès accomplis, les avancées au plan de la continuité à long terme de plusieurs systèmes d &apos; observation in situ demeurent limitées et qu &apos; il reste de vastes zones, en Afrique par exemple, pour lesquelles on ne dispose pas d &apos; observations ni de mesures in situ;
