You can use Landsat data from

http://earthexplorer.usgs.gov/

1. Convert the raw bands into Top of Atmosphere Radiance (TOAr).

2. Convert TOAr into degrees kelvin.

3. Convert degrees kelvin into degrees Fahrenheit or other.

These articles will show you the methods:

For LST retrieval, long-wave infra-red satellite observations are commonly used. Either single-band data along with a radiative transfer model, or a split-window technique (two adjacent TIR bands) to allow for atmospheric corrections (see Wan and Dozier, 1996). Such data are available from many sensors; the choice of sensor depends on the requirements of your study. You can find a lot of documentation and data in the webpage of EUMETSAT's Satellite Facility on Land Surface Analysis (http://landsaf.meteo.pt/)

You can retrieval LST from thermal bands of Landsat, ASTER, SEVIRI, AVHRR and Sentinel 3. There are different methods for estimate LST such as: Single-channel Algorithms, Split-Window algorithms and Multichannel Algorithms. The result be more accurate with doing Atmospheric and Emissivity correction.

For Landsat 8, you can look at this open access article:

Hi Partha

which satellite data are you using?

If it is a satellite with two thermal bands (like Landsat 8 or MODIS), the Split-Window (SW) algorithm is the best choice (easy and efficient). I myself used SW in three of my papers and found it accurate and easy to apply. Also, I used the online atmospheric correction tool provided by NASA (http://atmcorr.gsfc.nasa.gov/). This is also good but you can't apply it for entire image and it is point base. Also, I attached a file that are some parts of my own paper on LST estimation using Landsat 8 data. Hope it helps you.

Best wishes

Hi,  Use the Landsat 8 Band 10  or Landsat 6,7 band 6.2

read those files and check its data site and follow the steps:

and depend on ArcGis and envi to analyze the Image 

(( remember to subtract 273 to change K. to C))

you'll find full explanations of using envi program on net.

sorry because I've old files in Arabic language
