Standard names: *Riverine fluxes *

[StefanHagemann]

Hi I am working on riverine fluxes of various compounds that are transported within the rivers from land to the ocean. Currently, i want to publish some of may data at World Date Centre for Climate (WDCC) at DKRZ and noticed that my riverinenutrient fluxes do not have CF standard names.

Actually, there is no problem for my river runoff with the CF name "water_volume_transport_in_river_channel" (Unit: m3 s-1).

Hence, I suggest analogous names for the following riverine fluxes: Proposer: Stefan Hagemann, Institute of Coastal Systems, Helmholtz-Zentrum Hereon, Germany Date**: 12 June 2023

nitrogen_mass_transport_in_river_channel
Description: The amount of total nitrogen mass transported in the river channels from land into the ocean. This quantity can be provided at a certain location within the river network (over land) or at the river mouth (over ocean) where the river enters the ocean. Units: kg s-1 phosphorus_mass_transport_in_river_channel Description: The amount of total phosphorus mass transported in the river channels from land into the ocean. This quantity can be provided at a certain location within the river network (over land) or at the river mouth (over ocean) where the river enters the ocean.
Units: kg s-1 silicate_mass_transport_in_river_channel Description: The amount of silicate mass transported in the river channels from land into the ocean. This quantity can be provided at a certain location within the river network (over land) or at the river mouth (over ocean) where the river enters the ocean. Units: kg s-1 carbon_mass_transport_in_river_channel Description: The amount of total carbon mass transported in the river channels from land into the ocean. This quantity can be provided at a certain location within the river network (over land) or at the river mouth (over ocean) where the river enters the ocean. Units: kg s-1

Each of them has the typical mass_transport unit of kg s-1

Having, nitrogen (analogous for phosphorus with e.g. phosphate or carbon with e.g. DOC, DIC), and not nitrite, nitrate,etc. separately, provides the possibility to include all nitrogen compounds with the standard name.

What do you think on this proposal of new standard name for riverine fluxes?

Hi @StefanHagemann thank you for your proposals which @efisher008 has now added to the cfeditor (http://cfeditor.ceda.ac.uk/proposals/1) .

The names are well formatted and the units look fine.

Your definition of river_channel refers to "a certain location within the river network (over land) or at the river mouth (over ocean)". We have an existing standard_name water_volume_transport_in_river_channel whose description says "water flowing in the river channel and flood plain". Do your standard names also include flow within a flood plain and should we include that in their descriptions?

Best wishes Alison

Hi Alison ( @japamment ) thanks for your response. My defintion refers to all gridboxes within catchments plus their river mouths. I guess, the floodplain can be considered as part of a catchment. So, in order to be consistent with the existing definition, adding 'and floodplain' is ok for me.

Best regards Stefan

Hi @StefanHagemann,

I have updated the definitions of your proposed names to add 'and floodplain' into the text. These are visible in the CF editor here: http://cfeditor.ceda.ac.uk/proposals/1. For example: "This quantity can be provided at a certain location within the river network and floodplain (over land) or at the river mouth (over ocean) where the river enters the ocean." Please let me know if you would prefer a different phrasing.

Best wishes, Ellie

Hi @efisher008 thank you. The phrasing is good. Best regards Stefan

Hi @StefanHagemann,

Thank you for your message. The definitions seem to be agreed and I think these names are now ready to be accepted. Unless we receive any more comments on this issue within 7 days, the names will be accepted and go into the next standard names update.

Best regards, Ellie

Hello @StefanHagemann,

The time period mentioned above has now passed and so these names have been accepted. Thanks again for the proposal!

Best regards, Ellie
