<div><div dir="ltr">Well, in one example, you are reading data from the edge of the time series (t=1) and in the other you are reading from the middle. Are you doing some interpolation to get your data values? You should look at the output from ‘set lat 49’ ‘set lon 4.375’, ‘set t 1’, and ‘set t 8017’ and check the ‘q dims’ output to see if you’re really reading the grid elements you are expecting. <br></div><div dir="ltr">—Jenniferg<br></div><div dir="ltr"><br></div><div dir="ltr"><br></div><div dir="ltr">> On Mar 8, 2018, at 11:29 AM, Antoine Molin <<a href="mailto:amolin@plenr.fr" ymailto="mailto:amolin@plenr.fr">amolin@plenr.fr</a>> wrote:<br></div><div dir="ltr">> <br></div><div dir="ltr">> Hi,<br></div><div dir="ltr">> <br></div><div dir="ltr">> Thanks, but it doesn't change the bug.<br></div><div dir="ltr">> Antoine<br></div><div dir="ltr">> <br></div><div dir="ltr">> -----Message d'origine-----<br></div><div dir="ltr">> De : gradsusr [mailto:<a href="mailto:gradsusr-bounces@gradsusr.org" ymailto="mailto:gradsusr-bounces@gradsusr.org">gradsusr-bounces@gradsusr.org</a>] De la part de Jennifer M Adams<br></div><div dir="ltr">> Envoyé : mardi 6 mars 2018 12:53<br></div><div dir="ltr">> À : GrADS Users Forum<br></div><div dir="ltr">> Objet : Re: [gradsusr] mysterious bug with merra-2 data<br></div><div dir="ltr">> <br></div><div dir="ltr">> Try setting your tdef to be at 00z instead of 00:30z. <br></div><div dir="ltr">> —Jennifer<br></div><div dir="ltr">> <br></div><div dir="ltr">>> On Mar 2, 2018, at 9:11 AM, Antoine Molin <<a href="mailto:amolin@plenr.fr" ymailto="mailto:amolin@plenr.fr">amolin@plenr.fr</a>> wrote:<br></div><div dir="ltr">>> <br></div><div dir="ltr">>> Hi,<br></div><div dir="ltr">>> <br></div><div dir="ltr">>> I am using merra-2 data U&V wind speeds at 50m, for wind energy studies in France ;
