From: Dorothy Quincy [Dorothy.Quincy@noaa.gov] Subject: Dobson Data for 2006 Dobson data from Haute Provence is sparse due to instrument problems. Data from Lauder, Samoa, and Perth are missing at the beginning of the year as a result of an intercomparison in Melbourne, Australia. There were also some problems with both Lauder and Perth instruments later in the year (NH summer). The instrument in Peru was compared with D065 in Buenos Aires, and the data will need to be reprocessed. - WOUDC March 2007
