Land Information System Land Information System NASA created Land Information System (LIS) 3 year (FY02 – FY05) NASA ESTO Computational Technologies Project Goals: Realistic Land Surface Modeling High determination, High execution figuring Efficient information administration Interoperable & Portable

Slide 5

LIS Design - Extensibility Highly adaptable, configurable structure different areas LSM alternatives Meteorological constraining choices EnKF information absorption module (from GMAO) JCSDA CRTM interface (in advance, speculative FY10 discharge)

Slide 6

LIS Integration (IOC) Goals Goal 1 : LIS to completely supplant all AFWA Agriculture Meteorology (AGRMET) show capacities Precipitation, radiation, and surface driving calculations Grid preparing and GriB yield programming Goal 2 : Generate LIS items at higher determination ¼ degree determination limit for IOC Goal 3 : Demonstrate utilization of programming compactness, configurability, and review testing abilities 1-year turn up of introductory conditions preceding IOC; turn up \'warm-began\' from AGRMET Common framework empowers joint testing/assessment of programming/science changes High Performance Computing Center Program (HPCMP) Navy DoD Supercomputing Resource Center (DSRC) IBM bunch 1600 framework (Babbage). Babbage has 3072 aggregate 1.9 GHz CPU\'s Power5+ processors. Babbage utilizes a restrictive system and IBM\'s High Performance Switch (HPS), likewise know as Federation, to convey between hubs. The switch gives ~7-14 microsecond inactivity with a crude data transfer capacity of 2 GBps.

Slide 8

LIS - AFWA Initial Operational Configuration LIS AFWA IOC characterized as: Global ¼ degree determination, Latitude & Longitude lattice "AGRMET" surface meteorological compelling "AGRMET" precipitation constraining Surface perceptions METAR precipitation reports & display climate gauges Geostationary Infrared Precipitation appraise (GEOPRECIP) SSMI & SSMIS rain rate ecological information record AFWA World Wide Merged Cloud Analysis-based gauge Poleward of 50 degrees Climatology "AGRMET" radiation driving Relies upon AFWA World Wide Merged Cloud Analysis

Slide 9

IOC LIS instatement LIS executed "warm" AGRMET input information file beginning December, 2005 Dual document, AFWA dev/test & Navy DSRC on-line stockpiling Enables review testing of current and redesigned AFWA-LIS design by NASA and AFWA Month preceding IOC, finished 1-year review trial of LIS in AFWA arrangement Test likewise \'warm-began\' from ½ degree AGRMET information Week before usage, kept running continuously mode on test framework to bolster usage

Slide 10

Surface Forcing LIS IOC Meteorological Surface Forcing Lower troposphere temperature and stickiness profile NCEP GFS mixed with succinct perceptions Near surface winds got from 10-meter GFS winds If GFS is not accessible, NOGAPS utilized as a reinforcement

Slide 11

LIS IOC "AGRMET" Precipitation Forcing AFWA Blended Global Precipitation Estimate Barnes investigation strategy mixes perceptions from: Gage reports AFWA Geostationary IR satellite precipitation evaluate AFWA CDFSII precipitation assess DMSP SSM/I & SSMI/S rainrate gauges (Tropics just) Climatology Precipitation Forcing

Slide 12

LIS IOC "AGRMET" Radiation Forcing Shortwave Radiation Longwave Radiation Cloud data (scope, beat, sorts) from the AFWA CDFSII Reference: Shapiro (1987) References: Idso (1981) and Wachtmann (1975)

Slide 13

LIS Final Operational Configuration (FOC) FOC characterized as AGRMET killed Only ¼ degree LIS items accessible Support for WRF introduction Separate LIS space for each AFWA WRF area LIS areas coordinate determination/projection (matrix) of WRF space FOC probably planned for February, 2010 After FOC, plan to consistently build determination of worldwide framework as info information determination increments Coupled LIS-WRF framework to be finished FY2009 (April 2010), actualized late CY2010 (provisional)

Current LIS R&D Current LIS improvement endeavors

Slide 15

LIS Data Assimilation The non specific LIS-DA system as of now incorporates the NASA/GMAO EnKF module, and has been exhibited for soil dampness and snow cases (Kumar et al., AWR 2008): Added Tskin EnKF module and NASA/GMAO predisposition estimation module. EnKF and coordinate inclusion calculations officially incorporated into most recent LIS Version 6.0 discharge
