Abstract
The sensitivity of regional air quality model to various lateral and top boundary conditions is studied at 2 scales: a 60 km domain covering the whole USA and a 12 km domain over northeastern USA. Three global models (MOZART-NCAR, MOZART-GFDL and RAQMS) are used to drive the STEM-2K3 regional model with time-varied lateral and top boundary conditions (BCs). The regional simulations with different global BCs are examined using ICARTT aircraft measurements performed in the summer of 2004, and the simulations are shown to be sensitive to the boundary conditions from the global models, especially for relatively long-lived species, like CO and O3. Differences in the mean CO concentrations from three different global-model boundary conditions are as large as 40 ppbv, and the effects of the BCs on CO are shown to be important throughout the troposphere, even near surface. Top boundary conditions show strong effect on O3 predictions above 4 km. Over certain model grids, the model's sensitivity to BCs is found to depend not only on the distance from the domain's top and lateral boundaries, downwind/upwind situation, but also on regional emissions and species properties. The near-surface prediction over polluted area is usually not as sensitive to the variation of BCs, but to the magnitude of their background concentrations. We also test the sensitivity of model to temporal and spatial variations of the BCs by comparing the simulations with time-varied BCs to the corresponding simulations with time-mean and profile BCs. Removing the time variation of BCs leads to a significant bias on the variation prediction and sometime causes the bias in predicted mean values. The effect of model resolution on the BC sensitivity is also studied.

Three global models (MOZART-NCAR, MOZART-GFDL and RAQMS) are used to drive the STEM-2K3 regional model with time-varied lateral and top boundary conditions (BCs). The regional simulations with different global BCs are examined using ICARTT aircraft measurements performed in the summer of 2004, and the simulations are shown to be sensitive to the boundary conditions from the global models, especially for relatively long-lived species, like CO and O<sub>3</sub>. Differences in the mean CO concentrations from three different global-model boundary conditions are as large as 40 ppbv, and the effects of the BCs on CO are shown to be important throughout the troposphere, even near surface. Top boundary conditions show strong effect on O<sub>3</sub> predictions above 4 km. Over certain model grids, the model's sensitivity to BCs is found to depend not only on the distance from the domain's top and lateral boundaries, downwind/upwind situation, but also on regional emissions and species properties. The near-surface prediction over polluted area is usually not as sensitive to the variation of BCs, but to the magnitude of their background concentrations. We also test the sensitivity of model to temporal and spatial variations of the BCs by comparing the simulations with time-varied BCs to the corresponding simulations with time-mean and profile BCs. Removing the time variation of BCs leads to a significant bias on the variation prediction and sometime causes the bias in predicted mean values. The effect of model resolution on the BC sensitivity is also studied.</div></front></TEI><inist><standard h6="B"><pA><fA01 i1="01" i2="1"><s0>0148-0227</s0></fA01><fA03 i2="1"><s0>J. geophys. res.</s0></fA03><fA05><s2>112</s2></fA05><fA06><s2>D10</s2></fA06><fA08 i1="01" i2="1" l="ENG"><s1>Influence of lateral and top boundary conditions on regional air quality prediction : A multiscale study coupling regional and global chemical transport models : International Consortium for Atmospheric Research Transport and Transformation: North America to Europe, Part II</s1></fA08><fA11 i1="01" i2="1"><s1>YOUHUA TANG</s1></fA11><fA11 i1="02" i2="1"><s1>CARMICHAEL (Gregory R.)</s1></fA11><fA11 i1="03" i2="1"><s1>THONGBOONCHOO (Narisara)</s1></fA11><fA11 i1="04" i2="1"><s1>TIANFENG CHAI</s1></fA11><fA11 i1="05" i2="1"><s1>HOROWITZ (Larry W.)</s1></fA11><fA11 i1="06" i2="1"><s1>PIERCE (Robert B.)</s1></fA11><fA11 i1="07" i2="1"><s1>AL-SAADI (Jassim A.)</s1></fA11><fA11 i1="08" i2="1"><s1>PFISTER (Gabriele)</s1></fA11><fA11 i1="09" i2="1"><s1>VUKOVICH (Jeffrey M.)</s1></fA11><fA11 i1="10" i2="1"><s1>AVERY (Melody A.)</s1></fA11><fA11 i1="11" i2="1"><s1>SACHSE (Glen W.)</s1></fA11><fA11 i1="12" i2="1"><s1>RYERSON (Thomas B.)</s1></fA11><fA11 i1="13" i2="1"><s1>HOLLOWAY (John S.)</s1></fA11><fA11 i1="14" i2="1"><s1>ATLAS (Elliot L.)</s1></fA11><fA11 i1="15" i2="1"><s1>FLOCKE (Frank M.)</s1></fA11><fA11 i1="16" i2="1"><s1>WEBER (Rodney J.)</s1></fA11><fA11 i1="17" i2="1"><s1>HUEY (L.

Three global models (MOZART-NCAR, MOZART-GFDL and RAQMS) are used to drive the STEM-2K3 regional model with time-varied lateral and top boundary conditions (BCs). The regional simulations with different global BCs are examined using ICARTT aircraft measurements performed in the summer of 2004, and the simulations are shown to be sensitive to the boundary conditions from the global models, especially for relatively long-lived species, like CO and O<sub>3</sub>. Differences in the mean CO concentrations from three different global-model boundary conditions are as large as 40 ppbv, and the effects of the BCs on CO are shown to be important throughout the troposphere, even near surface. Top boundary conditions show strong effect on O<sub>3</sub> predictions above 4 km. Over certain model grids, the model's sensitivity to BCs is found to depend not only on the distance from the domain's top and lateral boundaries, downwind/upwind situation, but also on regional emissions and species properties. The near-surface prediction over polluted area is usually not as sensitive to the variation of BCs, but to the magnitude of their background concentrations. We also test the sensitivity of model to temporal and spatial variations of the BCs by comparing the simulations with time-varied BCs to the corresponding simulations with time-mean and profile BCs. Removing the time variation of BCs leads to a significant bias on the variation prediction and sometime causes the bias in predicted mean values. The effect of model resolution on the BC sensitivity is also studied.</s0></fC01><fC02 i1="01" i2="2"><s0>220</s0></fC02><fC02 i1="02" i2="3"><s0>001E</s0></fC02><fC02 i1="03" i2="2"><s0>001E01</s0></fC02><fC03 i1="01" i2="2" l="FRE"><s0>Condition aux limites</s0><s5>01</s5></fC03><fC03 i1="01" i2="2" l="ENG"><s0>boundary conditions</s0><s5>01</s5></fC03><fC03 i1="01" i2="2" l="SPA"><s0>Condiciones límites</s0><s5>01</s5></fC03><fC03 i1="02" i2="X" l="FRE"><s0>Echelon régional</s0><s5>02</s5></fC03><fC03 i1="02" i2="X" l="ENG"><s0>Regional scope</s0><s5>02</s5></fC03><fC03 i1="02" i2="X" l="SPA"><s0>Escala regional</s0><s5>02</s5></fC03><fC03 i1="03" i2="X" l="FRE"><s0>Qualité air</s0><s5>03</s5></fC03><fC03 i1="03" i2="X" l="ENG"><s0>Air quality</s0><s5>03</s5></fC03><fC03 i1="03" i2="X" l="SPA"><s0>Calidad aire</s0><s5>03</s5></fC03><fC03 i1="04" i2="2" l="FRE"><s0>Prévision</s0><s5>04</s5></fC03><fC03 i1="04" i2="2" l="ENG"><s0>prediction</s0><s5>04</s5></fC03><fC03 i1="04" i2="2" l="SPA"><s0>Previsión</s0><s5>04</s5></fC03><fC03 i1="05" i2="2" l="FRE"><s0>Couplage</s0><s5>05</s5></fC03><fC03 i1="05" i2="2" l="ENG"><s0>coupling</s0><s5>05</s5></fC03><fC03 i1="06" i2="2" l="FRE"><s0>Monde</s0><s5>06</s5></fC03><fC03 i1="06" i2="2" l="ENG"><s0>global</s0><s5>06</s5></fC03><fC03 i1="06" i2="2" l="SPA"><s0>Mundo</s0><s5>06</s5></fC03><fC03 i1="07" i2="2" l="FRE"><s0>Transport</s0><s5>07</s5></fC03><fC03 i1="07" i2="2" l="ENG"><s0>transport</s0><s5>07</s5></fC03><fC03 i1="07" i2="2" l="SPA"><s0>Transporte</s0><s5>07</s5></fC03><fC03 i1="08" i2="2" l="FRE"><s0>Modèle</s0><s5>08</s5></fC03><fC03 i1="08" i2="2" l="ENG"><s0>models</s0><s5>08</s5></fC03><fC03 i1="08" i2="2" l="SPA"><s0>Modelo</s0><s5>08</s5></fC03><fC03 i1="09" i2="2" l="FRE"><s0>Analyse sensibilité</s0><s5>09</s5></fC03><fC03 i1="09" i2="2" l="ENG"><s0>sensitivity analysis</s0><s5>09</s5></fC03><fC03 i1="10" i2="2" l="FRE"><s0>Simulation</s0><s5>10</s5></fC03><fC03 i1="10" i2="2" l="ENG"><s0>simulation</s0><s5>10</s5></fC03><fC03 i1="10" i2="2" l="SPA"><s0>Simulación</s0><s5>10</s5></fC03><fC03 i1="11" i2="X" l="FRE"><s0>Observation par avion</s0><s5>11</s5></fC03><fC03 i1="11" i2="X" l="ENG"><s0>Aircraft observation</s0><s5>11</s5></fC03><fC03 i1="11" i2="X" l="SPA"><s0>Observación por avión</s0><s5>11</s5></fC03><fC03 i1="12" i2="X" l="FRE"><s0>Eté</s0><s5>12</s5></fC03><fC03 i1="12" i2="X" l="ENG"><s0>Summer</s0><s5>12</s5></fC03><fC03 i1="12" i2="X" l="SPA"><s0>Verano</s0><s5>12</s5></fC03><fC03 i1="13" i2="2" l="FRE"><s0>Concentration</s0><s5>13</s5></fC03><fC03 i1="13" i2="2" l="ENG"><s0>concentration</s0><s5>13</s5></fC03><fC03 i1="13" i2="2" l="SPA"><s0>Concentración</s0><s5>13</s5></fC03><fC03 i1="14" i2="2" l="FRE"><s0>Troposphère</s0><s5>14</s5></fC03><fC03 i1="14" i2="2" l="ENG"><s0>troposphere</s0><s5>14</s5></fC03><fC03 i1="15" i2="2" l="FRE"><s0>Variation spatiale</s0><s5>15</s5></fC03><fC03 i1="15" i2="2" l="ENG"><s0>spatial variations</s0><s5>15</s5></fC03><fC03 i1="15" i2="2" l="SPA"><s0>Variación espacial</s0><s5>15</s5></fC03><fC03 i1="16" i2="2" l="FRE"><s0>Variation temporelle</s0><s5>16</s5></fC03><fC03 i1="16" i2="2" l="ENG"><s0>time variations</s0><s5>16</s5></fC03><fC03 i1="16" i2="2" l="SPA"><s0>Variación temporal</s0><s5>16</s5></fC03><fC03 i1="17" i2="2" l="FRE"><s0>Plomb</s0><s5>17</s5></fC03><fC03 i1="17" i2="2" l="ENG"><s0>lead</s0><s5>17</s5></fC03><fC03 i1="17" i2="2" l="SPA"><s0>Plomo</s0><s5>17</s5></fC03><fC03 i1="18" i2="X" l="FRE"><s0>Erreur systématique</s0><s5>18</s5></fC03><fC03 i1="18" i2="X" l="ENG"><s0>Bias</s0><s5>18</s5></fC03><fC03 i1="18" i2="X" l="SPA"><s0>Error sistemático</s0><s5>18</s5></fC03><fC03 i1="19" i2="2" l="FRE"><s0>Etats Unis</s0><s2>NG</s2><s5>61</s5></fC03><fC03 i1="19" i2="2" l="ENG"><s0>United States</s0><s2>NG</s2><s5>61</s5></fC03><fC03 i1="19" i2="2" l="SPA"><s0>Estados Unidos</s0><s2>NG</s2><s5>61</s5></fC03><fC07 i1="01" i2="2" l="FRE"><s0>Amérique du Nord</s0></fC07><fC07 i1="01" i2="2" l="ENG"><s0>North America</s0></fC07><fC07 i1="01" i2="2" l="SPA"><s0>America del norte</s0></fC07><fN21><s1>204</s1></fN21><fN44 i1="01"><s1>OTO</s1></fN44><fN82><s1>OTO</s1></fN82></pA></standard><server><NO>PASCAL 07-0317987 INIST</NO><ET>Influence of lateral and top boundary conditions on regional air quality prediction : A multiscale study coupling regional and global chemical transport models : International Consortium for Atmospheric Research Transport and Transformation: North America to Europe, Part II</ET><AU>YOUHUA TANG; CARMICHAEL (Gregory R.); THONGBOONCHOO (Narisara); TIANFENG CHAI; HOROWITZ (Larry W.); PIERCE (Robert B.); AL-SAADI (Jassim A.); PFISTER (Gabriele); VUKOVICH (Jeffrey M.); AVERY (Melody A.); SACHSE (Glen W.); RYERSON (Thomas B.); HOLLOWAY (John S.); ATLAS (Elliot L.); FLOCKE (Frank M.); WEBER (Rodney J.); HUEY (L.
