NIMBUS 1, 6 SEPTEMBER 196^1 



(Allison and Kennedy) 



NIMBUS 2, il6 AUGUST I966, 



(LaViolette and Chabot 1968b) 



All Nimbus 2 August data were cloud contaminated. On the night of 16 August, a 

 fine haze seemed to cover the entire study area uniformly. Thus, the temperatures record- 

 ed by Nimbus 2 for this night were approximately 12°to 15° F. lower in comparison to the 

 historical mean August chart. 



If the low temperature values are ignored, the horizontal gradients in the satellite 

 analysis visible through the uniform haze seem to show the pronounced upwelling along 

 the coast as well as the eastward extent of the cold water. The horizontal gradients are 

 strongest between 10° and 11° North with the gradient change of 15° F. This pattern is 

 close to the temperature differential found during the 1964 oceanographic cruise. If the 

 position of the horizontal gradients of Nimbus 2 and the cloud cover of Nimbus 1 are taken 

 as an indication of upwelling, the two satellite analyses are grossly similar. Both show 

 a more eastward extent of the upwelling than was found in the analysis of the 1964 ocean- 

 ographic cruise data.
