that protect the Nation’s citizens, businesses, mili-
tary, and government agencies, and enable such in-
dividuals and entities to operate in safe, efficient, 
and orderly manners.

ing or exceeding agency data quality standards, le-
verage existing networks of environmental moni-
toring stations, including supplemental radar sys-
tems, to increase the quantity and density of envi-

ministration. 
(3) Establish means to integrate greater density 
and type of environmental observations into the Pro-
gram on an annual basis, including by encouraging 
local and regional networks of environmental moni-
toring stations, in situ sensor networks and satellite 
constellations to participate in the Program. 
(4) Yield increased quantities of boundary-layer 
data to improve numerical weather prediction per-
formance, including regarding subseasonal to sea-
sonal timescales. 
(5) Provide the critical technical and adminis-
trative infrastructure needed to facilitate rapid inte-
gration and sustained use of new and emerging net-
works of environmental monitoring stations antici-
pated in coming years from non-Federal sources. 
(6) Expand and enhance environmental obser-
vational networks in the roadway environment to 
provide real-time road weather and surface condi-
tions for surface transportation and related eco-
nomic sectors. 
(7) Identify available terrestrial or marine envi-
ronmental data, or quantifiable gaps in such data, to 
improve the understanding of air-sea interactions.

reaching its target of a 30-minute warning time for 
severe weather through better predictive model algo-
rithms driven by increasingly effective observations.

data used for forecasts, including data from the Na-
tional Environmental Satellite, Data, and Informa-
tion Service, the Integrated Ocean Observing Sys-
tem, the Global Ocean Monitoring and Observing 
Program, the National Data Buoy Center, and the

assistance to State, Tribal, private, and academic 
entities seeking to build, expand, or upgrade equip-
ment and capacity of mesonet systems. Financial as-
sistance under this subsection may be made in co-
ordination with and in addition to awards from 
other Federal agencies. 
(2) AGREEMENTS.—Before receiving financial 
assistance under paragraph (1), the State, Tribal, 
private, or academic entity seeking financial assist-
ance under this subsection shall enter into an agree-
ment with the Under Secretary to provide data to

AND
OTHER
SUPPORT.—The 
Under Secretary may provide technical assistance, 
project implementation support, and guidance to 
State, Tribal, private, and academic entities seeking

assistance for maintenance of monitoring stations in 
underrepresented or remote areas of the country 
where it is financially unfeasible for one entity to op-
erate such stations without such assistance.
