The temperature data you load in has negative values, but you then take a ln(x)
transform on that.
We can instead first convert the temperature to Kelvin and use
[
# transform Celcius to Kelvin
fcbench.codecs.FixedOffsetScale(offset=-273.15, scale=1.0),
fcbench.codecs.Log(),
fcbench.codecs.Zfp(mode="fixed-accuracy", tolerance=1e-3),
]
Running the Zfp compressor on the Example data from here leads to the following error:
