While addressing a sub-optimal performance issue for interpolation from = the octahedral reduced Gaussian grid introduced with IFS cycle 41r2 to regu= lar latitude-longitude grids, a problem was discovered with the method used= to calculate the longitudinal points in the source grid. In some spe= cific cases, this problem leads to an incorrect computation of interpolatio= n weights and hence to incorrect interpolated values at some points of the = output grid.
The problem has been addressed in EMOSLIB versions 4.3.x. See Bug fix implemen= ted in EMOSLIB 4.3.x for further details.
[EMOS-252] - fix Cray failures on creating= and checking Legendre coefficients file size
[EMOS-260] - incorrect values for interpolation= to regular_ll particular sub-areas crossing 0 degrees longitude (particula= r cases)
[EMOS-262] - incorrect values for interpolation= to single points
This version of libemos was tested against BUFR tables ver= sion 000407, please check also changes of the previous version 000420
[EMOS-232] - include climate.v014 land-sea= masks
[EMOS-220] - fixed interpolation of wave model = parameters sub-areas straddling the Greenwich meridian
[EMOS-205] - smaller memory allocation for inte= rpolations of u/v on reduced_gg grids
[DAPP-249] - drifting buoys with new BUFR templ= ate (subtype 182)
