1. Algorithms Nine LST algorithms (Yu et al.,
2008) were analyzed for the land surface
temperature retrieval from GOES-R ABI sensor
data. Each of the algorithms consists of two
parts the basic split window algorithm and path
length correction (the last term in each
algorithm). The basic split window algorithms are
adapted or adopted from those published
literatures, while the path correction term is
added for additional atmospheric absorption
correction due to path length various.
Number of satellite and SURFRAD match-up
measurements.

• 6. Summary
• Split window LST algorithms were analyzed for
  GOES-R Mission LST EDR production.
• SUFRAD ground measurements were used for GOES-R
  LST algorithm evaluation
• Algorithms 2 and 6 are recommended for their less
  sensitivity to emissivity uncertainty.
• Algorithm coefficients are stratified for daytime
  and nighttime, dry and moist atmospheric
  conditions.
• Recommended algorithms will meet the GOES-R
  mission requirement (lt 2.4 K).
