title: Modeled isoprene emissions from NYC-MEGAN

description: This dataset included: (i) Modeled hourly biogenic isoprene emissions from
 the NYC-MEGAN (the Model of Emissions of Gases and Aerosols from Nature
 for New York City); (ii) modeled hourly chemical species concentrations
 from a box model. These model outputs are used for findings presented in
 the manuscript titled "High-resolution modeling of summertime
 biogenic isoprene emissions in New York City" by Dandan Wei, Cong
 Cao, Alexandra Karambelas, John Mak, Andrew Reinmann, and Roisin Commane
 published in Environmental Science & Technology.

 [https://doi.org/10.5061/dryad.00000009h](https://doi.org/10.5061/dryad.00000009h) This dataset include (i) hourly isoprene emissions from 30 meter spatial resolution NYC-MEGAN for the month of July, 2018; (ii) modeled future isoprene emissions from the experiments of different future urban greening scenarios; (iii) the box model outputs from the base run; and (iv) the box model outputs from experiments with different isoprene emissions future urban greening scenarios. ## The modeled biogenic isoprene emissions Files: ISOP_gram_per_grid_hour_201807xx_*.csv Naming conventions: * ISOP - isoprene * gram_per_grid - unit for isoprene emissions * hour - hourly data * 201807xx - the date in July 2018 * practical_canopy - the model scenario where we increased canopy cover by planting oak * practical_canopy_sameSpeciation - the model scenario where we increased canopy cover with current tree species composition Variables: * 0-23 (row): hour of the day, local time * column: grid of the domain Others: projection - EPSG32618 Spatial resolution - 30 meters ## The box model outputs Files: MOZART_4_base.csv MOZART_4_x.xx***NOx_isop1_4.csv MOZART_4_x.xx***NOx_isop2_2.csv Naming conventions: * MOZART_4 - Model for OZone and Related chemical Tracers version 4 * base - the base run with current NOx concentrations and current isoprene emissions * x.xx. - times current observed NOx concentrations that used to constrain the model * isop1_4 - experiment results where isoprene emissions are 1.4 times higher than current values * isop2_2 - experiment results where isoprene emissions are 2.2 times higher than current values Variables (details in Emmons et al., 2010); concentrations in ppbv: | variable | description | | :-------- | :--------------------------------------------------------------- | | time | model hour, local time | | O   | ground state atomic oxygen | | O1D   | excited state atomic oxygen | | O3  | ozone | | N2O  | nitrous oxide | | NO  | nitric oxide | | NO2  | nitrogen dioxide | | NO3  | nitrate radical | | HNO3  | nitric acid | | HO2NO2  | pernitric acid | | N2O5  | dinitrogen pentoxide | | H2  | molecular hydrogen | | OH  | hydroxyl radical | | HO2  | hydroperoxyl radical | | H2O2  | hydrogen peroxide C1 species | | CH4  | methane | | CO  | carbon monoxide | | CH3O2  | methylperoxy radical | | CH3OOH  | methyl hydroperoxide | | CH2O  | formaldehyde | | CH3OH  | methanol | | C2H4  | ethene | | C2H6  | ethane | | CH3CHO  | acetaldehyde | | C2H5OH  | ethanol | | EO  | HOCH2CH2O | | EO2  | HOCH2CH2O2 | | CH3COOH  | acetic acid | | GLYOXAL  | glyoxal | | GLYALD  | glycolaldehyde | | C2H5O2  | ethylperoxy radical | | C2H5OOH  | ethyl hydroperoxide | | CH3CO3  | acetylperoxy radical | | CH3COOOH  | peracetic acid | | PAN  | peroxy acetyl nitrate | | C3H6  | propene | | C3H8  | propane | | C3H7O2  | C3H7O2 | | C3H7OOH  | C3H7OOH | | PO2  | e.g., CH3CH(OO)CH2OH | | POOH  | e.g., CH3CH(OOH)CH2OH | | CH3COCH3  | acetone | | HYAC | hydroxyacetone | | CH3COCHO  | methylglyoxal | | RO2  | CH3COCH2O2 | | ROOH  | CH3COCH2OOH | | ONIT  | organic nitrate | | BIGENE | lumped alkenes C&gt; 3 | | ENEO2  | e.g., CH3CH(OH)CH(OO)CH3 | | MEK  | methyl ethyl ketone | | MEKO2  | CH3COCH(OO)CH3 | | MEKOOH  | CH3COCH(OOH)CH3 | | MVK  | methyl vinyl ketone | | MACR  | methacrolein | | MPAN  | methacryloyl peroxynitrate | | MACRO2  | peroxy radical from OH addition to MVK, MACR | | MACROOH   | model species | | MCO3  | peroxy radical derived from abstraction reaction of OH with MACR | | BIGALK  | lumped alkanes C&gt; 3 | | ALKO2  | C5H11O2 | | ALKOOH  | C5H11OOH | | ISOP  | isoprene | | ISOPO2  | peroxy radical derived from OH+ISOP | | ISOPOOH  | unsaturated hydroxyhydroperoxide | | HYDRALD  | lumped unsaturated hydroxycarbonyl | | XO2  | peroxy radical from OH+HYDRALD | | XOOH  | e.g., HOCH2C(OOH)CH3CH(OH)CHO | | BIGALD  | C5H6O2 unsaturated dicarbonyl, oxidation product of toluene | | ISOPNO3  | peroxy radical from NO3+ISOP | | ONITR  | lumped isoprene nitrate C7 species | | TOLUENE   | lumped aromatics | | CRESOL  | C6H4(CH3)(OH) | | TOLO2  | C7H9O5 | | TOLOOH  | C7H10O5 | | XOH   | C10 species | | C10H16   | lumped monoterpenes, as α-pinene | | TERPO2  | C10H16(OH)(OO) | | TERPOOH  | C10H16(OH)(OOH)  | | SO2  | sulfur dioxide | | DMS   | dimethyl sulfide | | NH3   | ammonia | | SO4  | sulfate | | H2O  | water vapor | | M  | air molecules |
