Conclusion 
Climate change has a significant impact on glaciers, 
which are very sensitive to changes in atmospheric 
conditions. Long term temperature observations over 
the glaciated terrains of the Himalaya can therefore 
provide a detailed understanding of climate change in 
the region. The main aim of this investigation was to 
examine a methodology for the estimation of Land 
surface temperatures from satellite data. The resulting 
estimated land surface temperatures were compared 
to NCEP modeled Surface temperature and the 
results showed a good correlation. The derived Land 
surface temperatures were compared with daily 
average mean surface temperatures modeled by the 
NCEP. The NCEP modeled temperature was found to 
be cooler than the extracted surface temperature, 
which is a realistic expectation. The results show that 
the satellite derived temperatures values are in the 
acceptable range. The present results show that 
satellite data can provide regionally representative 
values for surface temperatures, which is not possible 
from ground observations given the scarcity of data. 
The derived surface temperature values are found to 
be in good agreement with the field measured values, 
indicating that the methodology can be adopted for 
the Investigation over Himalayan region.
