Nonpersonal services to provide an atmospheric delta 13-C of CO2 modeling framework for interpretation and analysis of thirty years of air sample data.

PERFORMANCE WILL BE AT THE VENDOR LOCATION, BUT THE BETA.SAM IS HAVING ISSUES WITH THIS ADDRESS INPUT.

***NOAA'S ACQUISITION & GRANTS OFFICE, WESTERN ACQUISITION DIVISION-BOULDER, NATIONAL WEATHER SERVICE (NWS) PACIFIC REGION FACILITES ENGINEERING GROUP INTENDS TO NEGOTIATE, ON A SOLE SOURCE BASIS, UNDER AUTHORITY OF FAR 13.106-1(B)(1), WITH WAGENINGEN UNIVERSITEIT/ WAGENINGEN UNIVERSITY DROEVENDAALSESTEEG 4 6708 PB WAGENINGEN GELDERLAND NETHERLANDS FOR NONPERSONAL SERVICES TO PROVIDE AN ATMOSPHERIC DELTA 13-C OF CO2 MODELING FRAMEWORK FOR INTERPRETATION AND ANALYSIS OF THIRTY YEARS OF AIR SAMPLE DATA.

***THE SOLE SOURCE DETERMINATION IS BASED ON THE NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION'S (NOAA) “REQUIRES THE DEVELOPMENT OF A GLOBAL ATMOSPHERIC Δ13C (13C/12C OF CO2) MODELING FRAMEWORK TO ALLOW FOR BETTER INTERPRETATION OF ITS MANY THOUSANDS OF ATMOSPHERIC Δ13C MEASUREMENTS COLLECTED THROUGHOUT THE WORLD SINCE 1990.  INTERPRETATION AND ANALYSIS OF THIS DATA SET SUPPORTS NOAA’S AND GML’S MISSIONS BY HELPING TO UNDERSTAND THE REASONS BEHIND THE RISING CO2 LEVELS THAT RESULT IN CLIMATE CHANGE.  SPECIFICALLY, WE REQUIRE THAT THE MODELING FRAMEWORK: A) ENABLE HOURLY SIB4 BIOSPHERE MODEL SIMULATIONS OF ISOTOPIC DISCRIMINATION OF Δ¹³C IN CO₂ TO FEED INTO THE ATMOSPHERIC TRANSPORT MODEL TM5; B) PROPAGATE BIOSPHERIC DISEQUILIBRIUM SURFACE FLUXES OVER MULTIPLE DECADES INTO ATMOSPHERIC Δ¹³C OF CO₂, TO CREATE A CLOSED ATMOSPHERIC Δ¹³C OF CO2 BALANCE; AND C) INTEGRATE (A) AND (B) INTO THE CARBONTRACKER DATA ASSIMILATION SYSTEM FOR FORWARD MODELING AND EVALUATION OF ITS CO₂ FLUXES.  AIR QUALITY/ENVIRONMENTAL SCIENCES GROUP AT WAGENINGEN UNIVERSITY (THE NETHERLANDS) IS THE ONLY ENTITY IN THE WORLD CAPABLE OF DELIVERING ITEMS (A), (B), AND (C) LISTED IN ITEM 2 ABOVE.  SINCE 2012, THEY HAVE BEEN IMPLEMENTING AND REFINING 13C ISOTOPE SYSTEMATICS INTO THE PRECURSOR TO THE TERRESTRIAL BIOSPHERE MODEL SIB4.  THEY HAVE ALSO DEVELOPED UNIQUE STRATEGIES TO “CLOSE” THE 13C OF CO2 ATMOSPHERIC MASS BALANCE USING THE SIB4 BIOSPHERIC DISEQUILIBRIUM FLUXES.  FINALLY, THEY HAVE DEVELOPED AN ATMOSPHERIC MODELING SYSTEM CAPABLE OF SIMULATING ATMOSPHERIC CO2 AND 13C SIMULTANEOUSLY USING INPUTS FROM (A) AND (B) IN ADDITION TO OTHER PARAMETERS. THE WAGENINGEN UNIVERSITY GROUP HAS BEEN ABLE TO PUT THESE TOGETHER AS A COMPLETE PACKAGE.”

THE PERIOD OF PERFORMANCE IS FROM DATE OF AWARD THROUGH 6/30/2021 and two option years to go through 6/30/2023.
