Description
We were seeing too high capacity_factors for Offwind with weather year 2013 (still testing for 2019). That's probably due to too high wind speeds from atlite. They should be corrected by a scaling factor.
We already implemented a scaling for wake effects in wind parks. As a consequence the maximum power output of windfarms is reduced to 88.5% of their nominal capacity. This way we will probably see less grid expansion.
Adding another sacling of the capacity to account for overestimated wind speeds would lead to even less maximum output and even less grid expansion.
Therefore we should scale the windspeeds directly in atlite.
This has been discussed in https://github.com/PyPSA/pypsa-eur/issues/153 as well

Research direction
Start by reviewing the related discussion in PyPSA/pypsa-eur issue 153 and the atlite wind-speed handling. Compare the 2013 and 2019 Offwind capacity factors, determine an appropriate scaling approach, and consider the existing wake-effect scaling; done means the overestimated wind speeds are corrected without an additional downstream capacity scaling.
