Hi Ishtiaq,

Regarding your inquiry about the existing satellite images that provide a daily-basis temperature data, I would suggest to use MODIS data. It has half-day temporal resolution and is available at 250 m grid space worldwide. Through one of their product i.e. MOD11, you can directly acquire the land surface temperature. You can access the MODIS data on https://modis.gsfc.nasa.gov/data/dataprod/dataproducts.php?MOD_NUMBER=11

However, analyzing a day-by-day MODIS data can be tedious in particular if you are working with a long time epoch. For me, I prefer to use the results of climate change model that are available from trusted several climate change research groups. I suggest to use the climate change model from the group of Climatic Research Unit (University of East Anglia), since their results have been used in many published articles. You can access their datasets on https://crudata.uea.ac.uk/cru/data/temperature/

Hope it helps.

Regards,

I would also suggest you to use temperature data from models. But MODIS could also be a good option for comparison and particularly if you are going to work on complex topography.

Have an idea too here. best..
