[ecco-support] Monthly ECCO equivalent water heights

To point out the obvious, it should read "divide by gravity=9.81 m/s^2 to get equivalent m" below.

Or you can use:
ftp://mit.ecco-group.org/ecco_for_las/version_4/release2/nctiles_monthly/PHIBOT/<https://urldefense.proofpoint.com/v2/url?u=ftp-3A__mit.ecco-2Dgroup.org_ecco-5Ffor-5Flas_version-5F4_release2_nctiles-5Fmonthly_PHIBOT_&d=DwMGaQ&c=birp9sjcGzT9DCP3EIAtLA&r=1L8uucM1VfjzQOg3MBsQnQ&m=qim0N_ypR9bPnKF6Hd2RoZPgkB5GFsA1rw6Yy5S_j2s&s=TCCH4gtZ-e0mrEPzUNPzy8aa8uX0k5XXuWqtXWydFuE&e=>
which is bottom pressure in m^2/s^2
multiply by gravity=9.81 m/s^2 to get equivalent m
multiply by rhoConst=1029 kg/m^3 to convert to Pa

Hello

I want to compare equivalent water heights determined from GRACE gravity field models with ocean model results from ECCO.

I found that you offer daily ssh solutions to obtain equivalent water heights I have to remove the steric sea level anomalies, right? How do I determine the steric sea level anomalies or do you also offer equivalent water heights?

Do you also offer monthly mean solutions or do I have to determine the monthly mean solutions from the daily solutions myself?

Thank you very much
Franziska Göttl
