There have been a few issues about this already (e.g. #354, #556, #177)
The documentation currently states:
An important note about time: The outputstream code currently writes the end date of the current timestep in the outputstream.csv file; e.g., when we’re running 1 January 1745 - 31 December 1745, what gets written is “1746”. This is not intuitive (most people think of “1746” denoting January 1-December 31) but numerically correct: the date is 1746.0, i.e. midnight on December 31 1745. A consequence is that carbon fluxes logged at this timepoint are effectively for the calendar year 1745 (1745-01-01 to 1745-12-31).

As discussed in the linked issues, for NBP (formerly 'atm_land_flux') in simpleNbox it's not possible to retrieve a value for 1745 using RHector.
packageVersion("hector")
‘3.2.0’
core <- newcore('hector_ssp126.ini')
fetchvars(core, 1745:2100, vars = c(NBP()))
Error: sendmessage: msg: Interpolation requested but not allowed (?) date: 1745
func: get
file: tseries.hpp
ffile: ../inst/include/tseries.hpp
line: 332
With
fetchvars(core, 1746:2100, vars = c(NBP()))
I get (as expected and documented):
fetchvars(core, 1746:2100, vars = c(NBP()))
scenario year variable value units
1 Unnamed Hector core 1746 NBP -0.0802025172 Pg C/yr
2 Unnamed Hector core 1747 NBP -0.0762544017 Pg C/yr
However, in the command line outputstream I do get a value for 1745:
# Output from hector version 3.2.0 on Mon Feb 26 15:22:42 2024
year,run_name,spinup,component,variable,value,units
1745,ssp119,1,simpleNbox,NBP,0.0009932,Pg C/yr
1746,ssp119,0,simpleNbox,NBP,-0.0802,Pg C/yr
1747,ssp119,0,simpleNbox,NBP,-0.07625,Pg C/yr
For the Pyhector v3 update (openclimatedata/pyhector#63) I need to find a way to handle NBP not reporting for 1745, which in my current setup requests all years for all variables and errors with the same error as RHector above
.
I can surely work around this somehow, but was wondering why the command line version reports a value for 1745.
Also, is NBP the only value for which the start year (1745) is not being reported?
[Edited: I had 1746 in some places instead of 1745, sorry!]
