Erroe in GCAM7 modelface 'gdp-per-capita-ppp' unit?

[jiangyongye]

I was confused about the unit in GCAM7 Modelface 'gdp-per-capita-ppp' section, which is million 1990$ For example, SSP5 USA 2015 gdp-per-capita-ppp are 33.2204 million 1990$ which is not make sense. Could anyone help me with that?

Follow up! I checked the file zsocio_L102.GDP.R it said **The scenarios generated include the SSPs and the gSSPs (SSPs modified by

' near-term IMF projections). GDP outputs are in millions of 1990 USD, Market

' Exchange Rate (measured in 2010) is used for foreign currency. Per-capita

' values are in thousands of 1990 USD.**

so the unit should be thous 1990USD which it make much more sense : )

And i think why this error happen in GCAM7 but not happend in GCAM6 Because GCAM7 added marco_economy module, in GCAM 7 the code in Main_queries.xml for GDP-PER-CAPITA changed from

<gdpQueryBuilder title="GDP per capita MER by region">
            <axis1 name="region">region</axis1>
            <axis2 name="Year">gdp-per-capita-mer</axis2>
            <xPath buildList="true" dataName="gdp-per-capita-mer" group="false" sumAll="false">GDP/gdp-per-capita-mer/text()</xPath>

to

        <gdpQueryBuilder title="GDP per capita PPP by region">
            <axis1 name="region">region</axis1>
            <axis2 name="Year">nationalAccount[@year]</axis2>
            <xPath buildList="true" dataName="gdp-per-capita-ppp" group="false" sumAll="false">nationalAccount/account[@name = 'gdp-per-capita-ppp']/node()</xPath>

And i believe in nationalAccount the units are only million 1990US$ based on zsocio_L180.GDP_macro.R That's why it appear million 1990US in modelface, correct me if i understand wrong ： ）！

@jiangyongye good catch!

Yes, there were some unit discrepancies. It seems population in National Account should be thous as well. We will try to update these. Thanks!
