# Seeking MODIS Land Surface Temperature reference? [closed]

Can anyone point me toward an article that converts the LST values on the MODIS LST Image to degrees Celsius?

My purpose is find a reference (article, book or theses) for this formula that converts DN to degree celsius `(C=DN*.02-273.15)`

• Welcome to GIS StackExchange! As a new user, please take the tour to learn about our focused Q&A format. You have multiple tags on your question - are you using a particular software product? Your question is also unclear -- do you need assistance finding some MODIS documentation? – smiller Nov 29 '18 at 16:52

Your question is a little unclear, but I found this documentation

https://www.usgs.gov/media/videos/getting-started-modis-v6-land-surface-temperature-data-part-2

The Land Surface Temperature data is in degrees Kelvin. You can convert between Kelvin and Celsius through the formula below.

``````K − 273.15 = degC
``````

EDIT: after review of other questions on the site (once the OP clarified that they are looking for a reference for multiplying LST by 0.2), I found this answer which referred to the MODIS LST User Guide:

How do I convert the LST values on the MODIS LST Image to degree celsius. The documentation referenced is the actual user guide for Modis LST. https://icess.eri.ucsb.edu/modis/LstUsrGuide/usrguide_mod11.html#sds

Per the linked post, Temperature in °C will be: `DN * 0.02 - 273.15`

Verify which sensor your data is using just in case they have different calibration values and then look for the appropriate user guide.

Per the Modis 11 Level 2 Product user Guide:

The effective calibration formula for the "LST" SDS is LST = the SDS data in uint16 * 0.02, giving a value in the range of 150-1310.7K.
