( This status report is also available in ppt format).
Land surface temperature (LST) is one of the key parameters in the physics
of land surface processes, combining surface-atmosphere interactions and
the energy fluxes between the atmosphere and the ground.
LST is required for a wide variety of scientific studies -- from climatology
to hydrology to ecology and biogeology. For example, it is an important
factor in modeling large scale hydrological systems, global primary production,
and the greenhouse effect. Furthermore, it can be used in agricultural
applications (such as evaluating water requirements for wheat and determining
frost damage in orange groves). Status of the MODIS LST production as of 24 December
2001: the consistent reprocessing for
the collection-3 (version 3) product has been nearly completed for
the period from early November 2000 to the end of year 2001.
The global LST browse images are available from
the MODLAND web page (select
collection 3 and MOD11 (Surface Temperature), then click on Submit selectio.

what is the impact of the MODIS Cloudmask on the MODIS LST products?
how to screen off the cloud-contaminated LSTs in the LST products?
how to validate the surface temperature and emissivity in the 5km LST (MOD11B1)
product?
and what is the quality of the MOD11B1 product generated by the day/night LST
algorithm?

Status of the MODIS LST product as of 24 December 2001: the MODIS LST product has been validated with in situ measurements within 1K in 19 clear-sky cases (including 14 cases over land sites) in 2000 and 2001, in the temperature range of 263-322K and the column water vapor range of 0.4-3cm.
